The new (and only) Jamis dealer in town told me that there were no more 2012 Coda Sport (base model) to be had through his distributor. I imagine the first batch of the '13 models should be hitting the port to be loaded on to a ship any day now.
But don't be too hasty to judge the Giant shop. A simple eyes on assessment, when done by knowledgeable staff, can yield good results. Besides, those guys at REI might've been bored or needed the practice.
If you like that Escape, but not the shop that has it, you don't have to let them work on it.
