Places to buy a tarp that doesn't support MAGA?

Home Depot and Aldi's both seem to support trump to some degree, as does Amazon for online shopping. I feel that the only way things are going to change is through boycotts, strikes, and other ways of shifting the economy, but I'm really struggling to find places to buy stuff. I'm looking for a tarp to protect my tent from the rain while I sleep in the backyard (mental health thing suggested by my therapist). Anyone know places to buy something like that that aren't trump-aligned?
