His prices are extremely fair for ordered gear. They come already unlocked. so If you were to buy something that was 2,000 and it had 2 additional item slots, the first one I think takes 2,000 and the second one takes 6,000. But sometimes some gear takes more. So your 2,000 gear actually costs 10,000 when fully upgraded. You need about 10,000 points. Like his prices are exceptional sometimes. I bought some headsets, that have 2 unlockable perks, for 5,000.
He is probably the most fair vendor of all vendors lol. In fact, extremely fair. You don't ever have to play a game with a single perk from any gear you get from spyke. It's already maxed out, So obtaining more money with gear you just got from him, is easier than gear from any other vendor other than the weapons guy.
His 30,000 price tag for sea snails, is fair as well. If you are any good. it should take around an hour. It takes less than 30 games to accumulate 30g. Even less if you got the end of the day pay out. I get about as much cash as I do points. At least 1000 a game.
