Maybe you'd be best off selling them individually. A lot of people want the larger panels and do NOT want the smaller ones.
I am in search of the smaller ones. I'd like to buy the 1-rib, the 4-rib and the 5-rib (the three smallest ones.)
I'll paypal you $20 if you would ship those three to me. It will cost you under $1 if you throw them in a manilla envelope with a little newspaper.
Let me know.
