Glass bottles aren't very practical for large volumes that are gradually reducing as working solutions get partially discarded. I also don't have nitrogen and would have no clue how to get any.
I use 250ml bottles filled to the brim (to exclude air) one shot. It all depends on how long you want the developer to last. For my low volume, it is the best solutions. Nitrogen is obtained at any welding gas supplier, however, it does involve a great initial expense. Wine stores sell smaller bottles of inert gas at a higher cost that may be on option for some. YMMV
