Pay for your inventory.

There needs to be one or two more free retainers, or a bundle/discount for buying all 6 retainers. And not some bs discount like $1 off the entirety of the purchase, but $0.30-$1.00 off of each retainer

I'd even be willing to do a one off payment such as $20-$25 per retainer for life....
