Over the years I have bought by phone or online from many dealers. After a few disasters with deals that really were too good to be true, I only recommend buying new cameras from the major photo dealers like B&H, Adorama, or for underwater specialties from Reef, Optical Ocean, or Helix. I may pay a little more, but the stuff gets delivered reliably. Incidentally, always pay for such items with a credit card, not a debit card or other means. If something goes wrong with an online deal, credit card companies will usually support your getting a refund since the law requires that. Debit cards do not have that protection, and you are at the mercy of the merchant.
Regarding the original post, I suspect that Olympus is out of production on the Oly PT-EP01. They tend to concentrate on new products, and discontinue products without an announcement. I still suggest selling your E-PL1 and buying the newer model or switching to the XZ1, as others suggested, but if that is not what you want to do, I suggest acting quickly to get the PT-EP01 because stocks will dry up soon.
