This is a question you'll have to ask the company that is doing your printing. Is the profile up-to-date? Does it work with Aperture? Is it the correct profile for the prints you are ordering? Have other customer's successfully used it? Do they have any suggestions?
It may be that Aperture is not correctly interpreting the ICC profile, but even so you'd want to first confirm with your printing company that the profile works, that it works with Aperture, and that what you are seeing is _not_ correct for whatever paper/printer combination the profile represents. If they have other products with different profiles, you might compare them.

Kirby is of course right but I might add a few thoughts. Are you going from adobe98 or profoto to get to Costcos SRGB profile. First export your image as an SRGB and compare it to the costco image. you might just be seeing the difference between wide gamut profiles and small ones. Since you are using a profile then I can assume your monitor is profiled and up to date. If you are going from srgb to costco srgb and there is a big difference make changes to the image while soft proofing and run with that. Prints never come out right the first time through but profiles should help. Cheers

Thanks to you both. I spoke to one of the photo dept employees at our Costco - very nice, but didn't have a clue. I'll try Costco's website in the am, and hopefully that wil steer me in the right direction.
I did change the onscreen proofing to just SRGB and there was much less difference between my edited versions and the SRGB version. I might just go ahead and send one photo over with that profile, as a test.
And dbmoore - I haven't had my monitor color checked. I took the four week Aperture workshop at the local Apple store and the person teaching it was quite adamant that Apple products didn't need that. I must admit I was a little sceptical, but since it meant I didn't have to learn how to do it, I took the easy (lazy) way out. I'm guessing that maybe I'm going to have to suck it up and learn it. What product would you suggest?
I'll post back what I learn - thanks again

Im fond of xrite but the spider is good too. anything between 100 and 200 will be fine unless you plan on profiling your printer then it goes up from there. Check out Dry Creek Photo for latested Costco profiles and info http://www.drycreekphoto.com. Before you start to care about printer profiles you have to (should) calibrate you Monitor. Your house must be in order before you compare other houses. Cheers

I use and recommend the X-Rite ColorMunki Photo as a relatively inexpensive, reliable, useful spectrophotometer. X-Rite has a new product out -- Color Munki Smile? -- which is designed to provide exactly what you need at a much lower price than their full-range products.
Echoing dbmoore: you need to have a hardware-calibrated monitor in order to judge the accuracy of printing profiles. The whole system works by calibrating all devices to published standards. Printer profiles are not useful without a display profile. The hardware calibration makes a profile for your display, which you assign via the OS.
This post of mine -- and the items linked -- expand on this important topic.
