Wonderland gardens

Just got the “your order is cancelled” bs from wonderland gardens after placing my first order last Friday. It’s Tuesday, I figured it was gonna be in its way. Why tf does their website allow you to follow through with a transaction if they’re gonna cancel it for not being able to buy powder with a credit card? Why does the point of sale system even allow it to happen in the first place? Three fucking business days I could have placed an order with someone who was going to fulfill the order. Will not be amending the order fuck that place.
