Retail Marketing Mystery
Maybe I didn't pay enough attention in my marketing classes when I was in university, so that's why I'm having trouble understanding what happened a couple of days ago. Let's hope that my marketing and retailing expert friends can help me.
So we walked into a pretty well-known clothing retailer the other day after receiving a coupon promising a 35% discount on all items at their regular price. The cool thing about it is that it also entitles the holder to a 20% discount on all items that are already on sale. Not a terrible deal at all, don't you agree?
So after picking and trying on some articles of clothing, we get to the cash and present the coupon. The prices were already lowered on those items, so we thought that we would get the 20% off instead of the 35%. Fair enough.
The lady at the cash then says that the items we picked weren't at regular price so the 35% off wouldn't be applied. Fine, that's what we expected. However, the cashier then tells us that she can't give us the 20% off either. It turns out that the items weren't on sale. Instead, they were "on promotion". So they couldn't combine the offer with already existing promotions.
We ended up paying anyway because we needed the items. That and the "promotional price" wasn't terrible to begin with.
I'm actually more confused than annoyed. The question I'd like to throw out there to the experts is this: What's the difference between any retail item that's on sale and one that's on promotion? I was under the impression from previous experience with other clothing stores that they were the same thing.
Any ideas?
