Discount for patrons on the commission (Patreon)

I thought it would be fair for my patrons to get a discount on commissions. I also thought it would be fair enough for the discount to match the tier. For example, for $2 tier, the discount will be 2%, and for $10 tier, the discount will be 10%.

~ It will work the day after this post ~

Also I'm still open to commissions ^^
