I love going there .... ours has maternity as well, and I scored huge at the 'end' of winter sale, and got gobs of pieces of clothing (gap, old navy,mimi motherhood) for $1 each. I plan to call them Aug 1st, to see when they will be taking fall/winter stuff. I'll end up making money on the maternity clothes, since I got them so cheap.
I've had decent luck with both buying and selling children's clothes there. I think you probably get the better deals on the really tiny stuff, and the bigger (10 and up) sizes. For Rachel, she's able to wear 2T and some 3T. Prices are decent, but not phenomenal good deals. When Abby was able to wear 14s, we got loads of stuff there ... Abercrombie, Limited Too, etc for dirt cheap. In the newborn, 3-6 months stuff, there are MANY things with the tags still attached, for 3 and 4 bucks.
Selling is a whole 'nother ball game. A lot of times, it depends on their inventory. Mine has a sign inside the store that tells what they are really INO/ISO ... lists sizes, items (exersaucers, etc) that they want to buy. I've learned to CALL first before loading my crap in my car ... the last thing I want to do is load the big Rubbermaid tote in, only for them to tell me that they are not taking sizes under 4T.
Our OUAC gives you 50% of what they are going to sell the item for. In other words, if they charge $10 for an outfit, you get $5.
Sometimes, you could make more money on Ebay, yard sales, etc, but it's worth it to me, to get it out of my house in one fell swoop. (this is provided that they buy what I have)
I don't really do it for the money .... since I end up turning right around and spending it right there. I have a bag of DD#1s clothes that I was going to give to our niece, but first, I am stopping by OUAC, and seeing how I can make out there. Anything left over will go to our niece, and if I get any money, it will go to buy the boys some things.
I agree .... I would not drive 40 minutes .....
