I have never ordered from them myself but they have an excellent reputation. Look at Dave's Garden - Garden Watchdog.

They're good people to do business with.....

I didn't have such good luck with them. It took over a year to get my refund.

I've ordered from them a few times already. And I was very satisfied with them.They have good prices always gives a freebie when you order and sends you a coupon for another freebie when you place your next order.And if you look in the Canadian Gardening magazine annual 2007 issue they're also giving away 1 free hosta Golden Tiara with your spring order valid till April promo45.
I actually placed another order with them this spring.
