I see they have jacked up the prices again on the Texas Tomato Cages. They have a spot in the checkout for a coupon code--does anyone know if they ever do that? Or do they have a predictable sale, like Mother's Day or Father's Day? I never get any emails from them, although I likely checked out as a guest when I bought from them. If anyone is on their mailing list, do they advise of sales or give out coupon codes?
