Just bought some Epson cartridges last night (for a friend) and the sales assistant was good enough to tell me they were excluded from the 30 day return policy.
I just wondered why that would be, as the cartridges come hermatically sealed in plastic cartons (individual black and the other 3 colours separate). It's not like they could be tampered with and returned fraudulently. Plus they had the big Argos catalogue number sticker on them so it's not like I could have bought them elsewhere.

Our very local PC World had a few clearance softwares for sale, ranging in price from 47p to 97p. I took a selection, duly paid, and on checking at home, found one case had been tampered with at the bottom. The disk had been removed. Fair dues to PCW, they did provide a replacement.
