We're not great at writing these legal contract/terms things, so we'll keep this relatively simple: Dripcoins aren't an entitlement, they're just a way to thank you for your loyalty.
They're not some kind of promise, debt, contractual obligation, or I.O.U., etc. You didn’t sign anything, and neither did we. You don't have to pay anything extra to earn your Dripcoins, they're assigned to you based on the value of your order, and they're essentially just a gift which means if something goes horribly wrong and we have to stop offering them at some point in the future then we're not obligated to pay you for any Dripcoins you still have left at the time when we stop offering them. Of course, we don't have any plans to stop offering them, and if we do ever withdraw them we'll try to give everyone at least a week's notice, unless it's something out of our control.
Your Dripcoins are only valid at Vapoureyes NZ. Our sister company Vapoureyes Australia has a different rewards program, and since we're two separate companies operating in two separate countries there's no link between their rewards and our rewards.
Dripcoins are designed to be spent, not hoarded, so if you don't place an order within a month of receiving Dripcoins for a previous order we'll automatically deduct 250 from your account, and if you go 365 without using them your rewards account will be automatically closed and you'll lose whatever coins you had. That might sound mean to you, but remember that Dripcoins are free, you don't pay anything extra to earn them, and they're meant to be actively used.
