Photo: 261, Album: Brooklyn Camera/Electronic Dealer StoreFronts Active Atom, aka Power Seller NYC, Inc., dba PowerSellerNYC.com, aka DealCost.com 3670-3672 Nostrand Ave., Sheepshead Bay This address had been two outfits: 888 using 3674 and Marcus Audio Video using 3670. It is now combined inside. Web site now invites you to visit their retail store, but the address is not listed. Awning picture on the site lacks the Active-Atom name, but a June 2009 site visit found it the same as the picture here. One of the owners died, and a memorial is painted on a shutter. PowerSellerNYC appears in the DealCost code, plus there are a couple of suspicious reviews for PowerSellerNYC that are actually reviewing DealCost. It looks like the person pasting in the review pasted in the wrong ones! (DealCost's domain was registered with the address 2167 E. 21st St, Suite 142. This is a Mailboxes of Brooklyn that is 0.9 miles from here.)
