Best original prices were $464 p/p. checking for 2 weeks continually, current pricing rose to $494 p/p (most lkely due to rising oil prices) and Hotwire which lowest fare was $394 early on. After about 2 weeks of shopping, Priceline offered 5 counterfares. My bid was for $350 and the counter fare I accepted the $235 fare which was "non-jet aircraft and stay an extra day, 4/21/11", which meant a connecting flight in SFO with a prop, jet to SLC. Staying an extra day was no no-brainer using Priceline for an 3* Marriott Courtyard airport hotel at $42 for all 3 of us.
