I’ve noticed the 10/$10 a lot the last year; in fact, the Kroger near me is doing it this week. One interesting thing the Kroger did once: The ad had a full page broken into three sections, each section listed items that were being sold at prices like 10/$10, 3/$5, and 5/$7. The ad made it clear that you could mix items from each group, but you had to buy a multiple of 10, or 3, or 5 from the group to get the sale price. An interesting marketing plan, I thought.
I’m just amazed at all the accounts of these offers being nothing more than psychology - I never knew that sales technique even existed - here, whenever you see ‘buy 2 for X’, X is always less than twice the single unit price. I just never knew it was different (and pointless) anywhere else. Weird.
It certainly is that way in Toronto… I was totally incensed the first time I went to a grocery store here and tried to buy a case of Coke for $2.50… The store was advertising them at 2 for $5.00… It rang up at $4.29…
I asked to see the manager and told him it was a ridiculous policy - especially since the store is in the middle of downtown and the only people who shop there are nearby residents… Who the heck is going to carry two cases of Coke home on the subway or streetcar?
But I guess that’s the exact reason they do it… It looks like a great sale, but they probably sell very few cases at the discounted price.
Of course, they looked at me like I was insane to even question the policy…
I’ve since realized that it’s the same at all the grocery stores in Toronto… :eek:
Okay, maybe I wasn’t clear. Around here most of the big grocery stores give you the unit price on one, even if it’s a 2/something sale. But the sale price for each one is lower than the regular price. It’s like regular price $1.99, 2/3.00. So each one is 1.50, whether you buy two or not. I don’t think I’ve ever seen them do a 2fer with the regular price.
Even so, that seems really odd to me (mostly because it’s so alien to my experience, I expect) - if the unit price is temporarily reduced, alerting the shopper to the fact that he can buy two of them and pay twice the temporarily reduced unit price just seems completely redundant.
With a user name like Obeseus, I think the OP should just resolve the problem by abstaining from potato chips for a while. 
I noticed when they first started that 2 for $3 or 10 for $10 you had to buy the required amount. I think that has changed and you can buy 1 for $1.50 or 5 at a $1 each at least that what is like in the store I shop at.
I think it is different for the corner stores and gas stations. They set the register to ring up the first item at the original price and then the price adjusts when the second item is scanned.
The thing that always made me laugh is the buy one get one free ads. “Must buy two”. Well if I have to buy one to get the free one why would I not take the free one?
And in the case that I really only wanted one maybe due to lack of freezer or cupboard space are they going to force me to take the free one?
Buy one, get one free drives me nuts sometimes. The only sale my local Food Lion ever has on 2.5 pound bags of their house brand boneless, skinless chicken breasts or shrimp is buy one, get one free. I don’t have a lot of freezer space, and 5 pounds of chicken or shrimp lasts a long time when you’re living alone.
