Will I get burned if I don’t buy “this month”??

I am in the market for a new 570 EFi with Power Steering. After calling around to a couple of dealers to get some pricing I was told by both that I "SHOULD BUY BEFORE THE END OF THE MONTH BECAUSE THE REBATE OF $800.00 WOULD BE GOING AWAY". Is that true, or just sales jargon? Will there be some other rebate next month that will be just as good, like longer warranty and free winch or anything? I would prefer to buy in june or july when I have enough saved up to just pay cash, as i would rather not finance. Both of the salesmen said to just finance the rest and pay it off in the next couple months so that I can save the rebates. Sorry if this is a stupid question, I just don’t trust anything the salesmen say. Thanks
