The problem is with the SA vendors.
For years I have been saying that all vendors should have stock of a comprehensive collection of deck screws and o-rings.
This should also include parts such as 510s.
I have given the costs before. For the cost of a mod, they could have all the stock we need.
It is clearly done to prevent people from repairing their own attys and mods.
Their attitude is clearly that, if I stock a R30 510 connector I lose the sale of a new mod. If I stock a 25c screw I lose the sale of a R600 RTA.
Don't get me started on some of the SA Vendors ... I have a bottom drawer filled with useless "stuff" after listening to the advice of some of these so called experts advice as I embarked on my vape journey. I'm sad to say that the objective of a large majority of same is turnover, not industry support ... the good news is that this forum exists, making the sharing of information possible, and maybe the next step is as simple as a few group buys on the less common items?
