Right now through Plum District, you can pay $25 for $50 to spend at Barker Creek Publishing! They sell books and educational supplies – the one that jumped out at me the most was Draw Write Now, a curriculum that I haven’t used but have seen around here and there. They also have lots of workbooks, including Lasting Lessons (literature-based unit studies).
Shipping will be $8.90 when you redeem your Plum District voucher. Go here to see more of what Barker Creek offers, and go here to purchase the deal through Plum District.
