There's nothing quite like homemade.  
 
I know you can get hamburger buns cheaper elsewhere, on a per bun basis, mine are about twice the price.
 
But, what you get when you pay extra is real butter.  You get no preservatives or chemicals.  You get a hamburger/hot dog bun that isn't cotton fluff which comes apart when you put the burger and toppings on.  
 
$10 for a dozen.  I can also do half and half if you'd like:  half hot dog, half hamburger.
