Hi Robert,
With the exception of SurfWearHawaii FW, these suppliers aren't in our directory although they should be safe to deal with. They accept safe payment methods such as major credit cards and have been online for quite some time now. They may have offered wholesale then but seeing as this is an old post, I can't tell if that is still the case now. Try to contact them directly cause if they still do offer wholesale options, most probably, the prices listed on their site are retail.
All the best!
PS - This is SurfWearHawaii FW's wholesale website -
