Well as this thread is all about metal prices:
In Dublin, Ireland we only have few metal suppliers.
I am using 303/304 stainless.
Stock lengths here are 3 metres

So, if its small diameter no great problem (just get a lifetimes supply for the same price as a few feet from the ME shops [+p&p] in the UK

) but what about cut to length?
Then it becomes weird:
25 mm Round NO way - stock length
25 mm and over Square - no problemo "ctl" (naturallt also for 32 and 50 and above)
Round bar minimum "ctl" is 50 mm
Weird or what?
Must say however even to get suppliers to sell to me in small quantities (small: €100?) is an achievement.
BTW: If any Irish Mad Modders need some SS at cost price please PM me as I have 2.5 M of 25 mm bar! (plus a load of imperial round and hex from a long time ago)
So for info:
1" Round 303 3M €42 + vat @ 23%
5/8" Round 303 3M €17.40 + vat @ 23%
50mm sq. 304 Cut to 300 mm €27 + vat @ 23% [edit: forgot the price!]
