If you want stuff like spares don’t be afraid to buy nick nacks from China lots of them vend in here so you can see what they all got
I always use PayPal when buying from online ....that way you have some sort of cover if there’s a problem (I buy atomisers, mods and spares from china mainly I stick to buying batteries and wire from uk only)
Only risk by ordering abroad is you can get fucked if you get a problem cause shipping things back is obviously prohibitive but the trade off is lower prices, taking photos filling out forms blah blah, some are better than others for sure just be prepared to work for it all I’m sayin
I have ordered from US and Canada too but you’ll pay a shit load to the tax man just for the priveledge of receiving it ...be warned you can end up paying just as much if not more in shipping as the product
