I only use shipbikes now, most recently last week. The price is significantly lower then bikeflights, and I check side by side every time.

I have not found their website "clunky," but rather more straightforward then bikeflights.

I use their "pickup" option, which only costs $5.25. I used it last week, picking up a frame from an ebay seller in the Upper Midwest. He boxed up the frame, printed out the label and FedEx picked it up from his front door, and delivered it to mine for less than $30, including $100 insurance. I've elected more insurance on occasion, as it's about $2 per $100 increments. The pull down menu lets one choose, and going back and forth never loses my entered information.

The one quirk I've noticed about shipbikes is the ETA is usually inaccurate. They said that frame referenced above would get here tomorrow, but it arrived on Friday. It was picked up on Wednesday. Once they estimated a three day window, and it actually arrived the same day! Bikeflights seems to be all about getting it there the next day, while shipbikes is not. FedEx is very good about texting me and the other party regarding pickup, ETA, and eventual delivery, as is UPS, so it's really not an issue.

I had an item shipped from Charlotte from a CL listing, by a guy who didn't want to ship until I told him I'd have it picked up from his front door, and it was less then $20. I could not drive there and back again for that. Offering to have a package picked up from a distant CL seller has made the difference more than once. For that alone, at $5.25, they have my business. I think bikeflights offers that for $15? Five bucks and two bits to spare a seller from having to take the package to a center is an affordable courtesy.

Shipbikes' website has improved over the past two years, and especially over the past 6 months. Information entered on a transaction is saved until it's completed or cancelled, now, whether you have an account or, as in my case, not. I have been entirely satisfied with my shipbikes experiences.
