Replying to Insane good deal or Better quality?

I have been looking for a pair of new boots for a really long time, i just got a deal to buy some Hot doggers for 200 dollars with Volkl walls and bindings, the only problem is the size of the boot is 26.5.. I should be riding a 27.5. my last boots were 26's and my foot is pretty darn smashed. So my question is, should i get this awesome deal and possibly suffer a little pain during my season, or just go and buy some new boots for 300. advice please oh and also i could just buy the hot doggers for 100 seperate.
