Thanks, updated 
Gonna add in two AU battery sellers that I’ve had good experiences with:
Both are also on eBay, but cheaper on their direct website.
(getting anything over here is difficult!)

G0OSE, why do you say that TME requires a VAT number?
That’s not the case…

I have emailed all the battery suppliersthat don’t have a working code and asked if they could kindly help us out with a discount code (in the EU /USA so far) will update if I get a reply.
Updated with a new discount codes for Torchy (UK) and Battery Junction (USA) - thank you to the owners for getting back to me with these
Great thread. Thanks 
No worries, sadly it gets lost and not used much, nice to bump it now and again…took a lot of work lol. All the codes should be up to date as I emailed most of them this week.
