Goodwill Industries

During Covid, I have purchased almost 100 items from all over the country. I purchased a $7.99 shirt from a N Florida location. Many much larger/heavier boxes have cost around 8 when a shirt can just go in an envelope. The price they were charging me $1.99 handling (*no problem with that*), then $11.18 for shipping. I tried to discuss with the site, but got rude responses. I'd like to cancel as I do not agree with the purchase conditions. Total price ended up to $22.90... for a 7.99 shirt.
