what do you mean?

It means that while being a beta, I cannot offer it for free, so I would expect to get 90% of the value back. Let's say I give you a card with 10$ on it, and you spend it on a voucher or whatever,
if you're satisfied and confirm that it works, I would expect to get 9$ back from you to my BTC account. The $1 left can be kept by the beta tester. This is a beta for a service, he is not offering
free money

PS: Let me know if you're interested in a trial, I like your stats and you seem trustworthy.
