Many gift shops close because the owners stocked the shops based on what they like rather than what customers in the area will like.
You are not your customer.
This is especially true with gift buying. My experience is you will make more money with items you would not buy for yourself than from the items you love.
It is tough to disconnect from what you love when buying but you must.
I have had newsagents say they cannot sell items worth more than $20 who go on to find they can. I have also had newsagents say they cannot sell homewares who have found they can.
Please don’t let your prejudices and tastes hold you back from what you can achieve.
