Typically you have to click back twice to go from a product page back to the search results. It seems most common on distributor websites (90+% of the time, especially when signed in) though it does happen for me at times on merchant websites. This makes browsing our website very inconsistent and frustrating.
Furthermore, if the user clicks multiple vintages of an item, they have to click back over and over to go back through all the vintages and then back to search results. We at least need a "Back to search results" link to bypass this.
Combine these two things and users can get frustrated.
Thanks.
