No slip no exchange

<p>exchange bought pampers nappies at Checkers. Didn't check and bought 2 sizes to small. The said they will get the receipt electronically. Waited 10 min just for the manager telling me that they do not see the sale and that I can not exchange the nappies for a bigger size. It's a bigger size not a different make or anything, same price!!They did not want the help me. Now I'm stuck with 2 Jumbo packs. This is why I rather by from Baby Boom or take a lot!!!</p>
