Dollar Tree review: Masks

I understand the mask (mandate). I have a health condition that I cannot wear one. Yesterday I was in one the stores in Va and I stated that but they said I still had to wear one. Ok, then I will check out and go. I was told I could not check out with out a mask. I was told I could order online instead of coming to the store. That's fine except I don't get the same courtesy that everyone gets in the store. If we are refused into a store for not wearing a mask, then would you change the website so I can order what I need without having to be inconvenienced having to buy 25 of one thing?
Please change the website so it is fair to everyone. Every store offers online and curbside pick up but your store.
Thank you for willingness to be fair to everyone!
