Not from them lately, but just recently got a whole heap of them from droa.com (Domain Registry of America). Looks like a bill but it isn't, sent for wrong domain (.info rather than .com) and for domains I let expire etc. I can renew domains I own or don't even own and never have owned for the bargain price of only $25 per year! Woo hoo!!!
Too bad they didn't send postage paid envelopes or I would have been sending a lot of empty envelopes back to them.
