You missed out on the face mace by like a day or so. but other than that, it really depends on how much you have to spend. People buy nerkmids for 10-15k off, like 185-190k and sell them for 200-210k
You can also do morphing potions, but you gotta be a pretty good reseller, and it takes too much time imo.
Also I realized you can sell full WC maps. People buy full sets from shops, and then sell full sets for like +100-200k+ more than what they bought the set for. It's hardly noticable for the buyer since there are 20 pieces in each set. and if they win something good, they'll come back for more.
Like he said.. Nerks are GREAT!
Paint brushes are good too if you know what to get into and where.
I prefer ETS BD weapons. You can ALWAYS talk a seller down 1-2 mil on some of the higher ends and Sell for a big profit :o Depends on the seller!
yeah world challenge can make you quite a bit of money especially if you use a sser and you have multiple accounts, that would be an easy 1mil a day with multiple accounts
