Ok, quick update before I go to work.
Trina, I am so, so sorry... You're going to have to take the stuff to the PO.

I feel TERRIBLE that you have to do that. I talked to them on the phone, and they said those specific items can't go back to the store, and they're probably too big for the postman to pick up in his truck, so you'll have to take them in to the post office.
Prior to you doing this, I will print out pre-paid mailing labels and send them to you.
Once they receive the items, they will totally refund me, shipping and all. (Or so they say... I'm sure I'll have to call them again to make it really happen.)
Then I will replace the order.
The only good thing about this is that I'll get the gates for the new sale price.
I'm soooooo sorry you're going to have to lug that to the PO. I'll try to mail the labels to you before I leave Thurs, and then you can send them in whenever you get the chance. NO HURRY! (Oh, but you can probably give the little package--the feeding set--to the postman to take. That's small enough that he should be able to take it, so at least that will be one less thing you have to take in to the PO.)
Any chance James will take this stuff to the PO? Want me to call and beg him?
Also, don't send me the money you owe me from the gift card. We'll just count that toward the gas and effort you have to waste on this problem I created.
SORRY!!!
