Bloody hell! I can see why Blacks went bust.
Wandered into the local branch. Saw exactly what I wanted (some short hiking socks) & was pleased to see that they were marked as half price.
Went to till, & the price came up as full price. Salesperson told me that they were half price only if bought with footwear (as in shoes/boots/sandals). I politely queried the labelling, & was told in a rather challenging tone that it was on the labels. I said it wasn't obvious, & she came straight back with "I put the labels on myself" - which wasn't exactly an appropriate response, since I wasn't questioning either that they were labelled, or that the labels said what she claimed, only trying to suggest that small print in pale blue & white is not exactly conspicuous, & it might be wise to label conditional offers such as that more clearly, or more customers & potential customers would end up being irritated. But I didn't get as far as explaining all that. I gave up & left, without the socks.
I'm not sure if I'd have bought them if I'd seen the conditions on the label & expected to pay full price, but I certainly wasn't inclined to after having got as far as the till before discovering the price & then encountering a stroppy shop assistant.
I was passing Millets a few minutes later, & on impulse stepped inside to see if the same socks were on the same offer. Yup! But oddly, with different - and much clearer - labels. The small print was black on white, & hard to miss.
Well, their loss.
