I went to Going In Style yesterday to get more Forever New packets. There is no more Travelpro Platinum 5 at the store. The owner, Marilyn, doubted they had any left in the warehouse. She said they would have to drop ship Travelpro Platinum 5 from the maker. It sounds like they are no longer a source for Platinum 5.
I suggested she update the website to reflect that. I also suggested she read flyertalk for ideas on stuff to carry.
