Sears has the Propel Trampolines 15' Enclosed Trampoline w/ Anchor Kit which has a 300lb limit on sale for $249.99 w/ $52.50 back in sywr points. Free ship to store pickup.
I just picked mine up. Box is 50.4" x 18.1" x 16.5" weight 170lb.
I actually bought this for $280 a few weeks ago and when I went to pick it up it was not ready. Next day saw price had dropped and had $50 cashback so canceled order and re-bought, so saved myself $75 assuming I can find something to buy with the $50 cashback.
