A SMALL TOOL FOR A BETTER COMPARISON
Compare the pack.
Count the usable units.
Compare two packs of the same specification. Use the same tax basis and unit throughout: discs with discs, metres with metres, or pairs with pairs.
What makes a fair comparison?
Match the product specification, quality and unit first. Use the same VAT basis on both sides. Enter only units you can actually use, and allocate delivery consistently if it covers other products too. A lower unit cost does not establish product suitability or justify buying more than you need.
