I do quite a bit of online shopping and I'm trying to figure out which portal to use based on the dollar amount of each point/mile. I've been researching for a while now but the information is all over the place. I know different portals give you different point values but I am just really trying to determine how much each mile/point is worth. Here are the the programs I belong to. Each has its own shopping portal with various merchants: United Delta Marriott Wells Fargo - Seems to be an easy 1 cent per point. A $25 gift card will usually run you 2,500 points. Wish SPG had a way to earn star points with a shopping portal... I'm also a member of bigcrumbs.com. Haven't used it yet but let's throw it in there too. Thank you for your thoughts.
