B&H Photo has set up a page with the five Olympus E-M5 kits eligible for the VISA prepaid mail-in rebates. You can buy up to three lenses from the list of qualifying lenses shown in the PDF file which you can find under "More Rebates" in the middle of the page of individual product pages. By "individual product pages" we mean the individual page of a camera kit, for example, the silver E-M5 w/12-50 kit... For a more detailed discussion of these, see the main blog alert posted last week.
A note if you are buying these at retailers that have open marketplaces like Amazon, Sears, eBay, Best Buy, NewEgg, Buy.com, etc. Make sure you are buying from the actual house retailer itself, and not from third-party or marketplace sellers. If you are going to buy from a third-party/marketplace seller, make sure they are an authorized dealer and make sure they are offering this promotion through their Amazon/Sears/eBay/BestBuy/NewEgg/Buy.com listings, and make sure Olympus (and their rebate agents) are going to accept this as an eligible purchase. If you cannot verify all of the above, the safest thing to do is buy from the house retailer - if they are offering this promotion!
