H&M got another vote from me yesterday. My mum got some things for my nephew. Same item, two different colours but they went through at different prices (one had the lower price on a ticket, other one didn't have one). We queried it with the rather stroppy assistant who served us who blatently wasn't interested and wouldn't even go (or get someone to) go and check - she put the barcode number in again but that was quite pointless as it came up as it did the first time (I've since checked on the internet and the lower price was correct). We just left in the end.
