For everyone in the Chicago area I can confirm that both PMing and return/rebuy on the HDD and Ti200 will work at the BB in Bloomingdale, IL (by the Stratford mall, western burbs). The CSR I spoke with there was awesome...an older guy around 40ish, we had a nice little chat about how "bitchy" the pricks at BB HQ were. The guy told me he only worked nights because he had a "real job" during the day. Hehe...
I have pretty much every possible form now: sale, PM, and rebate receipts, plus rebate forms. I think I will send in the rebate receipts plus a copy of the sales receipt just to be sure, since BB will supposedly accept photocopies of receipts.
