If you’re buying a used car and it’s parked over a puddle – they don’t want you to look underneath.
Rental companies, specifically for vacation. They will say a certain condo/house is available on their website but then when you call, they’ll say it is now unavailable or just got booked very recently. Then they’ll try and show you a different place which is like $50 more a night, banking on the desperation of the tourists to just say “fuck it” and rent it.
Some stores increase the price of a product and then put it “on sale” by a percentage of the fake higher price.
Worked in a family owned pharmacy for a few years. Find yourself a family owned pharmacy if you a) don’t want to go through your insurance b) don’t have insurance or c) you’d like to support the working class and not walmart or CVS. People would call us and ask for a cash price for their medication. We would be hundreds of dollars cheaper than walmart on almost every prescription. I remember quoting someone a 90 day medication at $20 and they said walmart was going to charge $250. The reason I said the things about not going through insurance is because insurance companies tell the pharmacy how much to charge you and tell the pharmacy how much the medications cost. Shit, add insurance companies to this list. Family owned pharmacies are losing so much money because of the way insurance companies work.
When I worked at H&M we used to do some sneaky stuff with setting up the mannequins/displays. Whenever we had a supply of shirts that were really ugly, and weren’t selling well. We’d put the ugly item on the mannequin, and it would sell out very quickly.
This isn’t necessarily the dirtiest trick, but it worked pretty well for pushing really ugly clothes.
