She bought a toaster last summer at a sale. She used it, I guess, pretty often, but she only had it a couple of months when suddenly the plastic base of the toaster cracked wide open, and at the same time the heating system in the toaster burned out.She took it back to the store, but the clerk in the store said they wouldn’t take it back, and they wouldn’t give her money back, because she bought it on sale.
