After playing till level 14 in the Campaign, I found that I have no incentive to buy pizza! I love this game, but my items are consistently good enough to win all maps within 3 tries or less and I'm not interested in MP (I get stressed). I know that I'm a part of the more frugal audience, but there have been other F2P games were I spent money because they gave me something I wanted, the main examples being Tribes: Ascend and Path of Exile. Don't get me wrong, I really, really like the fact that I don't HAVE to spend any money, but I'd like to support the developers and now it just feels like giving a donation instead of buying something. For example, Club Membership sounds nice, but it's temporary (buying temporary things just feels wrong, I never buy boosts or equivalent stuff in other games) and it's pretty expensive too. Also, in my 20 hours of playing I haven't seen a single item in the club membership box that I couldn't just buy or find myself (just 1 rare, once, and I didn't even like that one) I think permanent membership at a reasonable price point (20-30$ worth of pizza) would sell better. I also would never buy chests, because at worst you waste money and at best you make the game easy. It could be just me, but I'd thought I'd state my views because I love this game and it's everything I hoped it to be since waiting for my beta key since last year.
