3 revenue streams.
Now, if I could only crank up the sales.
Been getting less and less since 2020…

Absolutely correct.
Good advice Don. We started on eBay and Amazon years ago and ventured onto other sites..mostly USA based so we got into trouble with wrong postage rates and having to cancel sales (as sold on one site and then another before we could cancel) Probably need to have an aggregator if selling the same stuff to avoid this. Not something to venture in without planning but fairly essential with the state of eBay and Amazon in the way they treat the small business owners.
I found this valuable quote while going through an old 1900s newspaper,
“The rule: “Do not put all your eggs in one basket,” does not apply to a man’s life-work. Put all your eggs in one basket, and then watch that basket, is the true doctrine the most valuable rule of all.” -Andrew Carnegie
eBay is far more than enough for most, especially for collectibles. No collector would overlook eBay. Other sites are massive time drains for trivial gain, especially when you factor in sales taxes which is something that eBay handles for us. You will need to file your sales taxes in every single state you sold to.
There’s no limit to your growth you can do on eBay. The only limits are those you put on yourself by believing you must go to another site to continue to grow, thus making it a self fulfilling prophecy.
I’ve been living by that Carnegie quote for multiple years and it’s served me well.
