Sure, I agree, we all are making money on them.. But i'm not talking about last year, or the present. I'm thinking ahead here. Not in the now, but in a few years...
Slave 1 will be so overly hoarded and while it's a great set, it's going to have a few thousand resellers holding it to start. I like the Sandcrawler, but slowly it's getting hoarded. If it goes past this year, forget it. It will have more than 200 people selling it at the base when it goes EOL, and that's just at the surface, because there will be thousands of others that have it waiting to list it at some other point... Ewok Village is already sitting at 150 some sellers on amazon. If it does go EOL this year, it's going to be like so many sets last year, and maybe even worse, and will not be profitable for all but those that used a lot of points, and bought at a discount.
When sets get that high in the number of sellers that have them, just like last year, they don't move and sit at basically a few profit margin above RRP for what's going to seem like years.. . There's so many others anymore. At that point, it's just volume that will win the game. Last year, the AT-AT's, Cantinas, and ISD's were a bit of a "surprise retirement" so many didn't stock those in time. This year, I don't see that as much. Already, there are more IST's than there were AT-AT's and ISD's this phase in the game. Just sayin'...
I agree, that buying at walmart's 50% discount is an easy way to make decent money. And that's going to be about the only way to do it at this point.
