did not receive marketing items

Bought an item from the FINAL CLEARANCE table yesterday, it was marked with a red sticker, as with the other sales items. Went in today to get more and I was told that they were no longer on sale. The \promotion\" ended, however everything else on that table was still marked down. When I asked the sales assistant how I was supposed to know that the \"promotion\" was ending YESTERDAY as there was no signage and had i know I would have gotten more yesterday, he, Prince, said nothing, just looked away as if I were talking to someone else. I eventually asked for the manager who had pretty much the same response \"nothing we can do, we didn't get know, nothing I can do\"... and that's it. Nothing you can do! I walk into a store, buy something on sale, and the next day, it's no longer on sale. However, the rest of he items still are??? Does that make any sense? That's aside from the fact that the don't care attitude has become something of a norm. Followed up by the discussion about the customer as they walk away. As if I'm being ridiculous asking why selected items have been taken off sale without being made aware. Shopping at @home seems to just be a matter of luck. "
