I found the brown wood box on the 75% off in BBW. The original price is $39.9. I thought it's fun to buy it if it's really 75% off. When this item was scanned, the price was $19.99. I told them I picked it up on the 75% off shelf. The sales person asked another sale person whether this one is 75%. The answer seems yes so that I got this kit for $10 finally.

BTW, I bouth it last Friday with some cheap candle and stress relief roll-on. Good luck!
