Olesen Sale 

When a company raises prices by a large percentage, then declares a sale on the same items for a smaller percentage, giving the impression of big savings but in reality pocketing higher profits than usual. References Little House on the Prairie episode "Harriet's Happenings" (1978) in which the Mrs. Oleson raises the price of her goods 50% but advertises a 30% discount. "We'll make a 20% profit!"

"This TV cost less money before Black Friday! What an Olesen Sale!"

yard sale 

A weekend cash-raising event where either you are selling strips of sod from your front lawn, or all the items for sale are three feet long.

I was gonna widen the asphalt parking-area in front of my house, so I carefully cut the grassy sod into easy-to-manage three-foot-long strips, neatly rolled it up and bagged it, and then held a yard sale.
