Decent deal for Weber LPG and NG - all 3 mentioned come with a free BBQ cover valued at $50 and free shipping. I know this has been slightly cheaper previously but still a great deal, particularly the Black LPG and NG models.
Thanks @1bug for additionl $20 coupon, I have updated the price.
While I don't know how the prices compare, when it comes to Weber BBQs I'd always recommend checking out the models from a specialist dealer. The extra features (for very little extra $$ when we bought our Weber Q - the medium size) are well worth it.
