My beautiful sisters in Christ!
We homeschool and belong to the HSLDA. There is a page on their website that shows the stores that will support HSLDA if you click through HSLDA's website. I had not seen the list of merchants, but it is HUGE! Everyone from barnes and noble to walmart to bass pro shops is on there.
Please consider clicking through HSLDA's page before online shopping. That is all you have to do. The retailer does the rest. Not only is this good for HSLDA, but also good for showing retailers that homeschoolers are a group to be supported. This might come in handy if (when) homeschooling is threatened at some point. We know that, frankly, the government (local to national) listens to money more than they listen to people. We could use retailers' support.
