Oh Yes, been on Amazon for about 15 years selling a very popular inexpensive brand that we used to sell around 300 -500 orders a week, now, let's see, today... 3 orders and over the weekend, Fri-Sun about 12 orders. It started about a 1-1 1/2 years ago and We tried everything. We stopped advertising because it's ridiculous to throw money away when Amazon is just pushing FBA even though it's more expensive and takes longer. Then we opened an eBay & Etsy store, and it seems like all the business has just moved to them. People are not stupid and will always search out the best prices & service. Oh well, what are you going to do...
