do you check each item when it arrives in the mail?

I ordered some footed sleepers from Old Navy a couple of months ago, intending for LO to wear them for Fall. We immediately washed the stuff and put it away. Last night I was dressing her after her bath and realized that ON had sent the wrong size (1 size smaller). I'm going to call them tomorrow to see what they can do but am not too hopeful seeing as the order was placed in early August and the PJs were washed. So annoyed! If anything, let this be a PSA that this stuff can happen with ON (happened last year with Gap too)!
