Just a guess, but I would recommend checking ebay for the cheap used books. Ebay is a good site for finding stuff that ships internationally. I switched to Amazon Canada and saw how outrageous the cost of the books were. God willing I'll do a cheap used book video here soon.
@@NepticFathers No print on demand for Canada and ebay is pretty empty of orthodox books in general. I think the only option is to find a store near the border and cross over for a day trip.
