I used to do this- I would go into Boots and write down the prices of all the products, then go over the road into Superdrug and do the same there. I only got asked to leave once, and you have to be very good at pretending that you are buying things! ie- have a basket. Then they change the store round, and it takes you 5 hours. For �12, looking back on it, it really wasn't worth it!
