WSP does indeed have slightly higher prices to help compensate for their shipping. /but/ in most cases I have found that after you calculate shipping on orders of any decent size, WSP is generally less expensive (Except in the Lye department....ED For lye on my end)
Lets do some quick math:
FO 1 scent from each place:
(I Took lemongrass sage and lemongrass Kiwi respectivly)
I will put put in () if they offer a size the other does not and give you a price comparison below
WSP: 2 oz: 5.95, 4 OZ: 8.95, 16 OZ: 35.95, Drum: (25 Lbs) 595.95
NG: 1oz:2.60 4oz:7.65 8oz:9.75 16oz:14.49 5lb:66.25 10lb:124.90 25lb:284.75
For WSP to have a 1 oz, 5lb, and 10lb it would be: 2.98, 119.19, and 238.38 respectivly if you broke down the costs of a 2 oz or a 25lb into those sizes. Keeping that in mind lets move on to shipping:
1 25lb Barrel from NG: 25.90 to ship to me.
1 8 oz bottle: 10.75 Cents!
That means a single 8 oz bottle = over 19.75 from NG, where as from WSP its 17.97 (35.95 /2)
Lets go with a medium size order of somthing they both have. 4 oz bottles. Lets buy half a dozen.
NG: 11.52 in shipping for a total of 57.42
WSP: 53.70
I am not trying to be confrontational I am trying to show you, and anyone newer reading this that its not about what you see on the site. Its about what the math breaks down to.
Having been a trucker for many years, I can tell you that in 80% of the cases, 'free shipping' is always a great deal unless you are getting over certian weight thresholds where they can get LTL or freight price reduction (Sometimes its as little as 20-30 pounds, some places its 200pounds +) in wich case you should do the math.
If you are going purely on numbers in my opinion it looks like the break even point (or where NG becomes better) is right around the 5-10lb mark (Extreamly good) but for order under 1 dozen 4 oz bottles or what not, based ONLY on money, WSP still seems better.
Thats just with FO, with their oils and such, I have found in most cases WSP is really good.
Hope this helps
