Not to get too far into the weeds on this, but this 20% coupon can net you FREE money if there isn't something you're interested in buying.

Imagine this scenario:

You have an item listed with BIN for $500.
You have your friend/spouse buy the item for $500.
Using the 20% coupon, (s)he pays only $400.
You pay eBay and paypal fees of approximately 13% on the $500 BIN price = $65.
You "ship" the card for free.

At this point, you've netted $35 for doing absolutely nothing.
Add in any eBay bucks, eBates promotions, and credit card cash back on the $400 purchase price, and now you're looking at another $4 to $16+ depending on the rewards programs you have.

$39-$50+ of free money.
