I've been looking at getting a Summit for my birthy (just over a month away), and I recently joined the tower savers club thing, to get the $50 off special coupon. So, a few weeks ago the Summit went up from 574.99 to 579.99 - not too big a deal - that's when they started officially offering the TQi radio, new body, LVC esc, etc. A few days ago I added a green one to my shopping cart there at Tower, just to experiment with coupon codes, etc, but didn't order it. Then, just this morning I look online, and the Summit has jumped up to $594.99! What the! Distressed about this, I notice at the top of the page, it indicates the total price of items in my shopping cart - still 579.99... also interesting. So, I open it up, and indeed, the summit is still available to me for 579.99 because it was already in my cart at that price. With my wife's blessing (always mandatory for a major purchase!), I pulled the plug on it, and ordered the green one at the old price. Phew, that was close!
So, FYI, it looks like if you have merchandise in your cart, they hold on to that for you for at least several days, and you can get the old price, if it's better!
I promised my wife I'd wait until my birthday to consider myself a new Summit owner- 5 more weeks! Torture! But I'll soon be joining your ranks!
