chromed plastic center console gear shift surround
two chromed plastic HVAC vent surrounds
chromed plastic center stack display surround
an aftermarket retractable cargo cover
Mazda all-weather floor mats

I suggest taking a look at the knowledge sharing document for all these items and more ideas.

Chocolate is correct Amazon and eBay will be top contenders (I think eBay is gonna be a bit better for most of these items because they are basically Chinese drop shippers).
However if you don't mind waiting (3+ weeks) then order directly from China. I personally have used
www.aliexpress.com for 5+ years easy. You set up and account, they verify your information, there are several payment options. You "buy" an item; or basically promise to pay. The seller ships the item (often free because China subsidizes shipping) and then you wait. Tracking is basically your item shipped. There is a count down timer; if the item does not get delivered by the expiration of that count down timer, you simply open a claim and the seller either sends a new one or you get a refund. Your item comes but not as expected open a claim, the seller fixes it or they don't get paid by Aliexpress. The most expensive item I have ordered was ~$100.00 (for my motorcycle) after making several $1, $2, $7, $15 purchases to test the process. Overall I have been happy with the vendors and the selling platform.
recent orders for me include:
