I've only used them once, by phone, and Pam was great at finding the paints I needed. I even called them (her) the next day to order some additional decal sets, and she remembered me from the day before. She got the decals in on the same shipment.
I've had some other e-buying experiences with other houses and they are all pretty much the same about notification (meaning, rather lacking on the info) but I've always received my stuff.
The only time I didn't receive something (from another supplier with the initials GM) was because they held up an entire order simply because one item was out of stock. A few emails back and forth took care of the problem, however.
Keep in mind that they are probably very busy people, and at the same time that we are looking to save a few pennies here and there from them, they are also doing the same in order to pass on the savings to us. A little kindly feedback goes a long way, also.
In general, I've found all of them to be honest and sincere in their attempts to serve us modelers.
I am glad that they are there, and what would we say if they suddenly went away?
Then again, that's just my opinion.
