Twice in the past week I have had to get into a discussion with a salesperson because of a clearly marked discount that they did not understand. And I mean this in the most generous sense possible: these were manufacturer's discounts the store was running on their behalf, not just some salesperson being dumb or oblivious. It was just obvious the store hadn't thought things through.
Both incident happened in the same store.
[Note: I'm about to enter and intensive 10-week course which will have me working 16 hour days so I'm stocking up on candies and cookies so I don't kill someone around week six. These will be kept in the car in case of me or other people emergency. Anyway...]
Now, tonight, I go in and see a deal which is 3 single serving Nabisco packs for $2. On the shelf were some Oreos, Chips Ahoy, something else, and Oreo Cakesters. All Nabisco, all single serving. I bring up three of the Cakesters because all the nom are mine thank you. Now the cakester packs, if you haven't seen them, are obviously a little larger than the others. But still single serving. Again, they ring up at something like $1.84 each and obviously not discounted. I start again, although this time I'm not as pushy because the sign says regular price is $.89 and these were clearly not that. But I did point out to the guy that he needs to move the cakesters in that case, since they're on the shelf with the things that are on sale and they have no price on them to let people know they're not. Winner = them :(
I know it's sometimes asking a lot of people, but please actually consider what you are actually offering before you commit to it. My examples are small scale, but they range all the way up to the guy who ended up winning an F-16 from Pepsi (who of course reneged).
