Earnable Sales Coupon

Let's say as a random drop from a loot box, or a bi-weekly reward for getting 3 honor points after a game, you get a sales ticket to get any skin worth 520 (and the 3 skins worth 390) for half off.

Then 3 of those tickets to turn it into a single sale for a skin worth 750, and then 3 of those for a skin worth 975, and then 3 of those for a skin worth 1350, then 3 of those for a Legendary skin sale, and then 3 of those for an Ultimate skin sale.
