Sweet! That would be the closest photo shop around for me. I'm not picky, I do like Kodak Tri-X the most but HP5 works for me. I'd buy Pan F but that's just me.
I think that having a fairly good supply of darkroom chemicals is good.
Non-Ilford and Kodak stuff that I could easily see myself buying would be;
Ethol LPD paper developer, Rodinal film developer..
Also Photographer's Formulary kits are nice (Van Dyke Brown/Kallitype/Platinum) too.
Negative sleeves, hanging bars.. I seem to buy sleeves and bars every couple of months. You can never have too many!
