when there are several items that will give you ECB's, do you have to do them in different transactions or will it give them all to you in the same transaction? (if i'm not making sense say the toothpaste i'm going to get says $1 ECB for buying it, plus the shampoo i want says $2ECB...do i have to ring them up separately?) i don't think you would have to, but i've never done this before and just want to make sure before my first trip so I know what I'm doing.
