I've placed a few orders and plan to continue using them as well.
I usually receive my order within two days and everything is packed with care. All items are taped closed and placed in ziploc bags according to type (shampoos separate from cleaning supplies, etc)
It is very convenient for me and actually saves me quite a bit of money and time, but that's mostly based on my location. I live in a rural area. Just this summer we got a new grocery store in the next town over (5 mins away), so I have been doing all of my food shopping there. The closest
Walmart (where I would do the rest of my shopping) is over 30 mins away. So, Alice saves me an hour round trip plus the gas.
It takes a bit of time initially to go through and select the items you want to have on your list, but it's very easy when you want to reorder and it's also nice to just click and see what items on your list have coupons so you can stock up even if you don't need that item right away.
I have found the prices to be about comparable to Walmart. Most items are only few cents cheaper, but I will buy items that have a coupon so I have been saving a bit more. For example, the shampoo I buy is $5.99 at Walmart. It's $5.41 on Alice and I used a $1 coupon, so I saved $1.58.
