WSP is my go-to "one stop shop" because no one else comes close to the variety of items they carry. They not only carry a HUGE selection of fragrance oils, but also a great assortment of colorants and molds. I have never had an issue with the quality of their products which means I can order with confidence.
Now that I've spoken about the good, I'll mention why I didn't give a full five stars.
WSP has gradually raised the prices on many of the items I purchase from them which means I can find the product elsewhere for a lower price. The $5 handling fee initially rubbed me the wrong way. I noticed there's a $7 free product coupon that I can use this month which makes up for the S&H irritation (Please continue with the coupons!).
I heard they changed many of their staff due to customer relation issues so I'm hesitant to mention I had one bad CS experience with them in the past. Hopefully their policies have changed if a customer makes a mistake with their order.
Lastly, their shipping does take quite a while which is frustrating. They market it as "free shipping" which makes most people ignore the negatives. I realize that they just hide the shipping cost in their raised item prices so I would like to see the turnaround time be a little better. They're also missing a huge opportunity by not selling unique bath bomb molds such as stainless steel and cute shaped molds like LUSH uses.
Overall they offer a huge assortment of items which is extremely convenient. They just released a coupon program which is great. They changed a bunch of staff so they could have a fresh start with customer service, showing that they are trying their best. You seriously can't beat the amount of awesome free recipes they have posted online. Unlike other companies they do not censor bad ratings on their products which shows honesty and allows their customers to make informed purchases.
No company is perfect, but WSP definitely is doing many things right.
