I haven't ordered from them, but there are lots of bad reviews of this company on Garden Watchdog. Here is a link that might be useful: Garden Watchdog - Specialty perennials

I used Webbs Water Gardens 3 years ago for my liner. That is the same company. I believe they shipped promptly but it was 3 years so I have forgotten the details. I thought at the time it was the best deal, but I may have missed something. They certainly treated me well or I would have remembered that. Remember, that roll is heavy. I got about the same size. ALSO if you spread out the liner on a lawn on a warm day, you will at least temporarily brown the grass. Fortunately it was mainly weeds and it sort of recovered.

I would stick with brands that have been out for a while and companies that have been around long. I would not like to find a product that worked well only to find I could no longer get it. I use NSR Green Leaves and General Hydroponics brands and have had great luck with them. You can buy these products online: http://www.generalhydroponics.com http://www.thegrowstore.com/index.asp Hope that helps.

I ordered from Violet Barn in the winter once a few years ago (I got a gift certificate for them for my winter birthday and couldn't wait to use it!). The plants were totally fine even though they spent some time on my porch in a Wisconsin winter before I got to them. I have ordered a number of other tender plants during winter and have never had any issues - though I am careful to only order from established sellers who are experienced at shipping plants during the winter. I usually don't order when it is bitterly cold (I wouldn't order plants when the temperatures are much lower than freezing, because apparently heat packs don't work in such low temps), but someone who knows what they're doing can usually get the plants to you safely even if you live in a very cold region like I do. If you are willing to pay for the Express shipping and it's not bitterly cold where you are, I think you will be fine ordering from Violet Barn in winter. Back when I ordered, they sent the plants in an insulated container.
