Although I haven't used Ilford film for years (been using Neopan) Ilford are looking better all the time despite being very expensive here. There's always mail order from, not the country of its origin, but the USA.
I just checked Cheapshotsau on the 'bay, there's not much difference between all of them. Foma's cheapest (obviously), but then it's a tight bunch between TMY/TMX for $36-38 (same as vanbar), FP4/Acros/TX/XP2/D100 $39, and Ektar/D400/Portra160/PanF $41-43 (cheaper than vanbar). All for 5 rolls of 135 and/or 120, so that's $7.20 - $8.40 each (although PanF/D100/XP2/D400 are all up at $48 in 135, but that's still way better than vanbar).
Still, for me, it's much of a muchness between the whole lot of them, these prices don't differentiate what I buy.
(and yeah, B+H is always cheaper, $25/5xFP4, but the shipping isn't worth it just for film. I always throw in a few rolls from there when I'm buying gear/hardware or paper though)
thankfully
