What I pay for 5 pair of garden gloves is what I could pay for 1 pair in the grocery store, and they wouldn't last as long. Forget about gloves from the garden store.
Absolutely, where and when you buy your gloves can save you lots of money. For me, having a supply of working gloves that I bought on sale has saved me lots of money over the years.
Just about anything purchased in the garden center costs 3X-5X more in my experience. You can often get a much better deal, and better product, in the hardware section of the same store.
