Me: Where did this [weird off-brand] shampoo come from?
SH: That's mine.
Me: Where did you get it?
Me: I thought you weren't shopping there any more.
SH: I got it months ago. It was free after rebate.
Me: Oh that's a good way to buy shampoo. [I myself buy the expensive hopefully won't strip all the Clairol #24 Clove from my hair golddigger shampoo, which costs a lot in beer units, although I have stocked up at the big Target sales.]
