COSTCO

My family's favorite store is Costco -my brother has a mini Costco in his house.
My sister-in-law usually does her Costco shopping on Mondays.
This week my brother told my sister in-law she should go on Sunday. Shabbos Hagadol my sister-in-law and brother are having A LOT of guests. Listening to her husband (that's what a good wife does) she went on Sunday.
When she got to Costco she saw that this might not of been the best day to come- THE PLACE WAS PACKED!
She always enters by the exit, because they have their flyers with the coupons there. (a little backwards) As she was entering a worker came over to her.
"You looking for a flyer?" she asked
"YUP!" she answered.
"I'm sorry, but were all out of them." she said.
My sister-in-law smiled, muttered under her breath "its all hp", and went to go get a wagon. There were only four wagons left. As she started her shopping she saw in the wagon was a new flyer that had all the coupons still in it. Looking through the flyer she saw that the coupons expired THAT DAY!
After she finished her shopping she compared her filled wagon with the flyer. EVERYTHING THAT SHE BOUGHT WAS ON SALE!!!!!
