I went to target to pick up jello. I bought 8 jellos and used 2 1/4 man Q and wanted to stack it with the 50/2 target Q (I had 4). The register would only accept 2 Target Q's with the 2 Man Q's. The manager said you can only use 1 man Q with 1 Target Q. My question is this-Should I have given the Target Q's first, then the Man Q in order to avoid the register rejecting the Target Q's?
