The best place to look for any accessory is actually
www.ebay.com! Sure you can pay retail but why when on Ebay.com you can buy half price? Now beware some are cheap in price because they are cheaply made. BUT you can do a search for an accessory and "oem" in the search... example: Sprint Centro oem case. You can buy used or new in the box. Nervous about doing a transaction with someone you don't know? Look at the sellers feedback. If they don't have a score of 100% satisfaction from their customers follow the prompts to read EXACTLY why the customer was dissatisfied and very important how often they've gotten negative feedback during their transactions. You also have the ability to purchase in an auction format or you can select a buy now option. But also check the buyers' shipping fee. Make sure they are reasonable. There you go. You now know the secrets.
