This was a mistake. Buyers will ask for discounts sometimes, and it’s a business decision on your part if you want to give it to them or not. Either way, the answer is, “sure, we have refunded you the difference, thanks for your business” or " we regret that we cannot offer a discount on this item. We appreciate your business." No other answer is really appropriate, and any other answer invites an escalating vortex of soul-sucking doom. There is no good outcome, so don’t.
I agree with the previous posts that this is both not a good idea and sort of useless. The only time I look up a customer is if I am having a problem with a shipping address and I want to make sure that the given address makes sense before I ship something.
The risk of a 1 star review on the item over this complaint seems fairly low. The greater risk would be negative feedback on your account.
Every order has the possibility of resulting in bad feedback. Unless it’s your first hundred orders or so, I am a strong advocate of doing what you need to take care of your business. Living in constant fear of negative feedback is bad for your business and your health. If you think the best business decision is to take the item back, then take it back. Otherwise, don’t let the worry of potential negative feedback drive you into giving away free money.
AtoZ claims can be opened for up to 90 days, just like feedback, so this might be a risk. However, the buyer opening a claim isn’t the end of the world, and your metrics only take a hit if you lose the claim. In this case the odds of you winning the claim would be pretty good since the buyer doesn’t really have anything to file a claim for.
How you handle each AtoZ depends on the claim reason the buyer used. If they open a claim for INR, for example, then you focus strictly on the issue of tracking and delivery, regardless of what other complaints the buyer may have made. Assuming you used Amazon’s shipping and the tracking shows a scan proving you shipped on time, you should win INR claims.
In this case, the buyer has limited options to open a claim, and you should be able to defend all of them. Unless you didn’t use Amazon’s shipping, you can defend INR claims as the buyer clearly has the item. The buyer never opened a return request so they can’t make any claims about you not refunding. In short, I don’t think there is much danger from a potential AtoZ claim.
Unfortunately, that ship may have sailed when you answered her about how other sellers were selling for more and you were going to raise your price. Regardless, the choice you have now is to:
A) give the buyer a label to send the item back and a full refund, thereby doing everything you can to try to make the buyer happy,
B) tell the buyer to send the item back at their expense and then refund based on the condition of the returned item, which might sound like a reasonable compromise but in my experience will just upset the buyer further because you aren’t giving free returns and a full refund, or
C) tell the buyer that Amazon’s return window of 30 days for returns has passed and you can no longer accept the return.
Considering the previous interactions with this buyer, I would choose option C simply to end the issue before it gets any worse.
