Tough acclimation
06/18/2014 By James Abel

Came delivered in great shape but had a great deal of trouble acclimating. Most are still very wilted after watering profusely for a week now. Half look like they're past the point of no return. I personally rec getting them already potted. Those took off immediately.

James,

"Watering profusely" is what is harming them. Read the "Care" tab on the page you ordered from, it states:

The main reason why we recommend that you do not plant Hedera ivies in the summer is because it is tricky to water enough without over-watering.

You must let the soil dry out between watering, but not so much that the plants die. Stick your finger three inches into the soil, if you feel any moisture at all, do not water them.

The "Shipping" tab also cautions you against planting this time of the year unless you know what you are doing:

Unless you know what you're doing, we do not recommend planting any Hedera ivies without a good month to get established before the heat of summer. We strongly recommend that you plant before mid-April or after mid-September (up to May 1 is OK in northern zones). It's tricky to water enough without over-watering (you must let the soil dry out between watering, but no so much that the plants die).
