I remember answering that :D

Answer remains the same(-ish), but now covers dp or gp and product if found:

I used the old link for reference:

urls := ["https://www.amazon.com/Lenovo-IdeaPad-17IML05-Notebook-81WC0015US/dp/B08FMD9FK5/ref=sr_1_2?dchild=1&qid=1631950075&refinements=p_n_feature_twenty-two_browse-bin%3A23447271011%2Cp_89%3ALenovo%2Cp_36%3A2421890011%2Cp_n_size_browse-bin%3A7817234011%2Cp_n_feature_four_browse-bin%3A2289792011&rnid=676578011&s=pc&sr=1-2"
    ,    "https://www.amazon.com/gp/product/B0713WPGLL/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1"]
for _, url in urls {
    RegExMatch(url, "\/[dg]p\/(product\/)?\w+", linkId)
    MsgBox 0x40,, % "http://amazon.com" linkId
}

    Insert::
AmazonLinkStripper() {
        ; Debug
        ; Clipboard := "https://www.amazon.com/Lenovo-IdeaPad-17IML05-Notebook-81WC0015US/dp/B08FMD9FK5/ref=sr_1_2?dchild=1&qid=1631950075&refinements=p_n_feature_twenty-two_browse-bin%3A23447271011%2Cp_89%3ALenovo%2Cp_36%3A2421890011%2Cp_n_size_browse-bin%3A7817234011%2Cp_n_feature_four_browse-bin%3A2289792011&rnid=676578011&s=pc&sr=1-2"

    RegExMatch(Clipboard, "(https:\/\/www\.amazon\.com\/)(?:.*\/)(dp\/.*\/)", match)
    if (match1 != "https://www.amazon.com/")
        return
    res := match1 match2

        ; Debug
    MsgBox, 0x40040, A_ThisFunc, "res: " res

    return, res
}

Copy your URL, then run this function. This works for the given example. I recommend getting the GetURL() into your code to improve this further.

Edit: Reverted MsgBox from a function back to a native command.
