With the introduction of crates and crate drops, the value of donating for cubes has been debatably vastly over-inflated. With that in mind we've gone ahead and simplified the amount you get as well, making it generally easier to know how much you're getting. So from today, it costs $1.50 for 50,000 cubes. Anyone that has donated for cubes in the last 3 months will receive additional cubes topping up what they originally donated for. If on the donate page calculator it's showing you the old values, please hard refresh or delete your cache for it to update correctly.
