There are no betta clubs in Delaware but that doesn't mean there aren't breeders. I would try contacting some of these clubs to see if they know anyone near you. If they don't there will be breeders who would be willing to sell you their bettas... it would cost much less than having a betta shipped from overseas.
I've heard it only cost about $8 more and isn't as big of a deal as people who haven't done it make it out to be (myself included). The thing that annoys me is the $35 it'd cost to have it shipped from the transhipper overnight.
I guess it depends on how much you like the betta you found and how much you'd pay for it.
If you but from a domestic breeder you shouldn't have to go through a transhipper. Thats why I will always get my bettas from domestic breeders unless I absolutely fall head over heels in love with one on aquabid and want it for breeding.
I would never pay more than $30 for a pet betta. (including shipping)
