"Buy One Get One Free", "Get Three for the Price of Two", "Buy 3 for $20"... Comparing product prices can be tricky at the best of times, but it gets considerably more difficult when you factor in all of the sales promotion techniques used by retailers. BOGOF Price Comparison cuts through all of the confusion and the complex calculations.

There are other price comparison apps, but in most cases the information they provide can already be determined by searching a product's price tag for its 'unit price'. Unit pricing allows shoppers to compare the value of products of different sizes by giving their cost per 100g, per fl oz, per kg, or any other unit of measurement. While this is helpful for price comparisons, the problem with unit pricing is that is no longer accurate when a sales promotion is applied to a product. That's where BOGOF comes in, allowing you compare the costs of products - regardless of the pricing promotion used - and quickly find the one that saves you money.

Whether you're in your local supermarket, shopping online or simply looking at ads in a newspaper, BOGOF will ensure that you always get the best possible deal.

So, which is the better buy? Six-packs of 500ml beverages (costing £7.50 each) in a "Get 3 for the Price of 2" offer OR a crate of twenty 12fl oz beverages that normally costs £15, but has a 10% deduction off the marked price. With BOGOF you'll have the answer, and be saving money, in seconds.

BOGOF is a price comparison tool, but even if you only enter information on one product you'll still get lots of useful information about the savings on a particular offer.
