I think NS does free shipping over $35 and WSP does free shipping over $25 (but they have a "handling fee" which stinks).
There is this supplier on ETSY that does free shipping. I have heard of fragrance buddy, but never personally bought or used their fragrances for soap because I find their website a little hard to navigate (honestly, while they explain exactly what they do, I'm still confused). But I think other people have used their f/o's for soaping and they do ship for free

There are a few sellers on ETSY that seem to have less pricey shipping (one had shipping at like $3.85). However, they seem to be from sellers I don't know.
Do you do social media? I wonder if there is a way for you to connect with someone nearby and place a large enough order to get free shipping or someone you can split the shipping with, so its not as high a cost? Once again, this suggestion is very conceptual for me as I do not really do not do social media, but, to me, if I were new to soaping, I'd kinda want a known brand, like NS, WSP or BB.
But if splitting costs isn't a possibility, you can probably do a little research into fragrancebuddy and order some of their f/o from ETSY. LOL, I hope someone has a better answer than mine!
