Well, maybe you can return the chemical if it's not used? Some things in life aren't worth the hassle, and roses are supposed to be fun. The nursery I go to will sometimes do special orders, maybe there's one near you that would do the same.
That, or there's a website www.heirloomroses.com , which has Collette with free shipping. I've never bought from them but might be worth checking into. Heirloom Roses has an A+ rating with BBB.
