welding caps

Hi, I’m new to Etsy (the selling part)
been buying from Etsy since 2012.
Between my friend and I I think we have everything except shipping! I’ve been making welding caps and shipping all over the USA since 2012, I use priority mail, “if it fits it ships” and it works great. The post office sends free shipping supplies and I only have 2 shipping prices, $8.55 and $7.95. Every now and then I have to go ship a box, not often. I’ve never had problems with my welders paying shipping.
Can I have it…
