First: I'm not affiliated in any way with Macodirect and if moderators find this message being unfair advertisement, it's absolutely fine by be to delete it. Or move it, if it's not appropriate forum. I'm just APX100 addict.
Just found that macodirect has sale on APX100 30,5m/100ft bulk rolls, 5 rolls for EUR89.94, which makes 17.99 roll. Looks like reasonable price to stock up with this wonderful and gone emulsion.
