Readywares waxed canvas products on Amazon currently have double stacking coupons totaling 30% off, which make for some pretty good deals. I haven't seen these go on sale this much. I have several of their products, and have been really impressed with the quality for the price.
You have to clip the 15% off coupon on the product page, then apply the coupon code F5GXLMJA for a stacking 15% off.
