Cost Per Unit on eBay

The Problem

eBay is one of the largest and most competitive online marketplaces for all kinds of products. When it comes to those sold by the unit, weight, length, volume etc eBay's size can become a problem. With thousands of listings returned for many common products it is impossible to find the one that is the best value.

eBay features a cost per unit measure on some listings but we have found it to be wrong a lot. Many listings are what eBay calls 'mult variant', meaning that the single listing contains variations of the product and one of these is often the quantity being sold. Each variation of quantity will have a different cost per unit and there is no way to find out what that is on eBay unless you click on every listing and check every variation on offer. Sorting by price therefore doesn't work either as there are often variations for sample sizes which may be cheap but their cost per unit is very high.

What We Do

After becoming frustrated with the problem of being unable to sort on price per unit in eBay we decided to build a solution. We check eBay regularly for a range of popular products and our unique software assesses each listing. We extract the quantity on offer from all listings and their variations, calculate the cost per unit and display the listings on our site sorted by cost per unit.

Because of the errors some sellers make when listing their products for sale we can't interpret everything correctly but we make it much easier to find the best bargains on eBay at any given time. We are adding new products all the time and we earn a small commission for our effort should you go on to make a purchase.

If there's a product you'd like to see on our site please contact us on our Instagram account and we will look into it.

The Complete Guide to Mold and Mildew Removal Sprays

Mold and mildew are common household problems that can cause unsightly stains, unpleasant odors, and potential health issues. Specialized cleaning sprays offer an effective solution for removing these fungal growths and preventing their return. This guide covers everything you need to know about choosing and using mold and mildew removal sprays effectively.

What's in Mold and Mildew Removal Sprays?

These specialized cleaners typically contain one or more of the following active ingredients:

• Bleach (Sodium hypochlorite): Effective for surface mold on non-porous surfaces, kills spores on contact
• Hydrogen peroxide: A less harsh alternative to bleach that's effective against most mold types
• Vinegar (Acetic acid): Natural solution that kills about 82% of mold species
• Tea tree oil: Natural fungicide with antimicrobial properties
• Quaternary ammonium compounds: Common in commercial mold cleaners, effective disinfectants
• Concrobium: A patented formula that kills mold and leaves a protective coating

Active Ingredient Comparison

Ingredient	Effectiveness	Safety	Best For
Bleach	High (surface mold)	Low (harsh fumes)	Non-porous surfaces like tiles
Hydrogen Peroxide	High	Medium	Most surfaces including fabrics
Vinegar	Medium	High	Small areas, natural cleaning
Tea Tree Oil	Medium	High	Prevention, mild cases

How to Use Mold Removal Sprays Effectively

Expert Tip: Always wear gloves and ensure proper ventilation when using mold removal products.

1. Preparation: Open windows and turn on ventilation fans. Wear protective gloves and a mask if sensitive.
2. Initial treatment: Spray generously on affected area until thoroughly wet.
3. Dwell time: Allow the product to sit for 5-15 minutes (check label instructions).
4. Agitation: For stubborn mold, gently scrub with a soft brush (avoid abrasive tools that can damage surfaces).
5. Rinsing: Some products require rinsing, others don't - check the label.
6. Drying: Ensure the area dries completely to prevent regrowth.
7. Prevention: Consider using a mold inhibitor spray after cleaning.

Surfaces That Require Special Attention

Important: Some surfaces need special care when treating mold:

• Drywall: Porous material may need professional treatment if mold has penetrated deeply
• Wood: Can be damaged by bleach - use oxygen-based cleaners instead
• Fabrics: Test on inconspicuous area first, some sprays may discolor
• Electronic devices: Never spray directly - use a damp cloth with cleaner instead
• Antiques/delicate surfaces: Consult a specialist before treatment

Health and Safety Considerations

When dealing with mold and mildew cleaners:

• Never mix different mold cleaners (especially bleach with ammonia or vinegar)
• Work in well-ventilated areas to avoid fume buildup
• Wear protective gloves to prevent skin irritation
• Consider an N95 mask if you have respiratory sensitivities
• Keep children and pets away during and immediately after application
• Store products in their original containers away from heat sources

Getting the Best Value for Your Money

To maximize your cleaning budget:

• Consider concentrate formulas that you can dilute as needed
• Look for dual-action formulas that both clean and prevent future growth
• Compare active ingredient percentages - higher concentrations may work better
• Check coverage area - some premium sprays cover more square footage
• Read reviews for real-world effectiveness on similar mold problems
• Buy in bulk if you have chronic mold issues in your area

Smart Shopper Tip: For occasional use, smaller bottles may be more economical as some products lose effectiveness over time after opening.

When to Call a Professional

While sprays work well for surface mold, consider professional help when:

• The moldy area is larger than 10 square feet
• Mold keeps returning despite treatment
• You suspect hidden mold (musty odors but no visible growth)
• The mold is in your HVAC system
• You or family members experience health symptoms related to mold exposure

By understanding how mold removal sprays work and using them correctly, you can maintain a healthier home environment while getting the best value from your cleaning products.
