So I know I shouldn't share this as it might not work (not tested) and also too many people might exploit it and it will go away (if it works) but.... I was thinking you could use the SW shopping portal at drugstore dot com to buy SW gift cards and earn 4 points per dollar then use them for travel and earn the regular points in addition. Plus you could earn points on the spend on your miles or points credit card. Will it work. I haven't seen any reason why not but I haven't tested it either.
