I just performed an experiment.
Freestyle Photographic charges $111.00 for insured SIMS shipping of 4 one gallon packets of each of Kodak D-76, Dektol and Fixer plus an 8 ounce bottle of Photo-flo.
The total cost of your order would be just under $200.00 USD.
The shipping is expensive, but that would last you a long time.
If you add a selection of their Arista EDU Ultra VC RC paper the shipping price would go up, but 225 sheets spread between 5x7 (100), 8x10 (100) and 11x14 (25) would only add $30 in shipping and $103 for the paper itself (shipped Priority Mail International).
