You mentioned boosting your savings, which is great. What kind of stuff did you find actually sold the fastest (I always get stuck with the slow-moving junk)?
Actually, the stuff that sells fastest for me is clothes and shoes, especially brand names (even if they're a bit worn). @carter.john, I used to get stuck with old electronics forever, but people always need something to wear. Just make sure you wash everything and take pictures in good light. Small kitchen gadgets do okay, but they can sit for weeks waiting for the right buyer.
