QVC will have easy pay on certain items at certain times. It may have been that the easy pay you saw was due to expire by the end of the day or weekend. It all depends.
There are a lot of easy pay options when Dooney shows are on, especially when they have events where there are several shows in a weekend. I would bet there will be a lot of easy pays during the November TSV. The Santorini is new so there is a good chance it will be on easy pay again, because they tend to present the new bags often. Good luck.
