Now here is one thing I am sure you may not have known....
Since you're buying at a store and not online,and the store happens to be in our state (Florida) you will be paying state taxes with the purchase.
Now if you buy from danscomp.com (out of Ohio) you pay no sales tax and danscomp.com offers great deals like promotion codes for 10%,15%,and 20% off your orders total or free shipping (free shipping won't save you as much as the others will).
Shop around at danscomp.com and use promo code 41da at checkout for 15% off your order (excluding Odyssey/G-Sport,FIT,and S&M products).
I see you're looking for DK BMX under $280 in a local store....Well I know for a fact that DK only offers four bikes under or at $280 not including shipping (if you order online) or sales tax (if you buy locally)...these bikes are...
DK Siklon
DK Sentry
DK Sentry 24" Cruiser
DK Cygnus 20"
In my opinion if spending that little amoutn of money on a bike I would choose the DK Cygnus as it sports a chromoly main frame (toptube,downtube,seat tube,and head tube are made from chromoly tubing) because chromoly tubing is both lighter and stronger then hi-tensile steel tubing of the same thickness and diameter.
The DK Cygnus is a Park/Trail inspired frame so it will be fine for street,park/vert,and dirt jumping.It doesn't come with the greates of parts but it's better then the DK Siklon.
The DK Sentry and DK Sentry 24" cruiser are racing frames and parts not meant for street,park/vert,or true dirt jumping/trail riding.
