I think your missing the big picture. See frugality is blind - rich or poor. I have wealthy and poor friends who are frugal. OP is trying to turn a profit while the items is still hot and he did resell. You see an angle and try to hit that angle of paying less overall. Could be less overall price of them item or cost of ownership. The overall value your getting for the item. Frugal does take some effort but its worth it if your getting something you want at a good overall value. And sometimes it works and sometimes it doesn't.
For alot people, screw that. They get a second job or buy used super cheap. I mean whatever works. But practice frugal, you'd be surprised the buying power overall.
