From their site:
"For one week only (or while supplies last), we’ll pick out a random assortment of 10 CDs or 3 TAPES from throughout our entire catalog of releases and ship it to your door.
To ensure that we can send these out in a timely manner, we aren’t able to take any requests, but we promise not to send you any duplicates!
Limit one per customer.
Hurry — this great deal will only be available for one week (through 5/31), but may end sooner if supplies run low!"
Looks like shipping starts at $3. Not bad if you’re looking for some new music.
