I pre-ordered a pair of Jennen shoes (elevator shoes, so I can be a big boy) from their online site (they no longer have the shopfront on Johnstone street) and got asked for a tip at the end. For basically changing a stock allocation assignment. I had a whinge on their contact forms, and they replied "the tip function is optional".
2 years later I emailed again, saying "I haven't bought a replacement pair of shoes, all because of the audacity to ask for a tip. I get that it's optional, but so is a cashier going 'hey give me that twenty from your wallet', and when the customer goes 'wtf??' the cashier replies 'oh lol it's optional'. You may have thought 'you know, a tip screen could give us free money! What's the harm?', and I guess this follow up email is proof of that harm. Don't bring tipping culture here please!"
I get this reply a day later, and can confirm the tip function is now gone. Loverly! Whinging may be one thing, but persistent whinging made the difference.
I was in the market for a docking station. There was a particular brand that was showing up in recommendations, was well-rated, and had the specs I was looking for. I found it on Amazon, but I avoid buying from that place as much as possible, so I checked the vendor's website directly.
They had the dock for sale on their own website, so I proceeded to purchase from there. However, when I was almost done with checking out, I saw that they were asking for / suggesting a tip. That's honestly despicable for an online store and way past the line for me. So, I did some more research, found a different brand of dock, and bought that instead.
Looking back, I should have done what you did and notify jsaux of their missed sale, but I honestly just assumed it was a pointless endeavor. Maybe one day I'll go back and see if it's still there on their checkout, and if so, let them know they've missed at least one sale.
You can do it now
