I've mentioned that I like Royall Products before and my most favorite one is Royall Muske. I sometimes keep a page open on Amazon and check the current pricing. I purchased three 8 oz. bottles in 2016 from Amazon for $36.00 a bottle not including shipping and it had tax added as well. A while back there were listings in the $40 range with shipping and more recently in the $50 range with shipping for the same product and last week I saw listings from the same company for $65 with shipping and today it is back down to $55 with shipping! Royall's current online price from their website is $70 a bottle with shipping. What's going on with all these changes in pricing? Tariffs? Exchange rates?
