You might be overthinking it.
When it comes to your items for sale, any extra exposure is good exposure.
To me it doesn’t matter where I sell it as long as I sell it!

Importing from eBay allows you to easily put your eBay inventory on Bonanza, saving you the time of listing those items on Bonanza. There is no cost to using this Bonanza feature. When you are importing your items from eBay, you have the option to reduce the selling price for your newly imported Bonanza item. That helps differentiate your items on Google Shopping and, hopefully, buyers will see the cheaper item on Bonanza and purchase here.

Using Bonanza’s publish to eBay (aka advertising on eBay) feature allows you to list your Bonanza items on eBay. For that publishing service, Bonanza charges a 1.5% service fee. That gets paid to Bonanza while you pay whatever eBay listing fees and FVF on whatever your normal rate is there. When publishing to eBay, you can automatically add a price increase so that your eBay prices are higher than your Bonanza prices. This could cover the 1.5% surcharge that Bonanza charges for their service.

When you are “syncing” your items (which keeps the inventory the same on both sites), the inventory on both sites is maintained properly so that you don’t sell on one site and forget to remove the item on the other site.

I agree with you. I have some items on eBay, but I do not have them synced. Etsy does not sync with eBay and I don’t think any other does either.

There’s very little engagement on this site. I don’t know why they don’t push the site more on social Media.

There are tons of sites where Advertising is very inexpensive (Free).

YouTube is Free. Why don’t they have a Good YouTube Viral Marketing Program. Everything on YouTube pops up 1st in Googles Search Rankings for Free because Google owns YouTube.

Same with TikTok. Free to Create engagement.

Same with almost all of the Social Media sites.

Even their Affiliate Program has only a 3 day expiration, Where most offer 30 days minimum.

They have a YouTube Channel, but they only post a few times a year, and the Videos are so Bland and unengaging. They’d do better just having a Video Blog with someone broadcasting from their Spare Bedroom.

I really like this Platform, but they aren’t doing much to promote it. I don’t know many people who even know it exists.

I just think there are a lot of Cheap and/or Free Methods of spreading the word about it, but they just aren’t doing it.

I can’t avoid the eBay, Amazon, Etsy, Poshmark Selling groups even when I try. but I just can’t find anything about Bonanza even when I try to look for it.

What if they gave us an option to sign up for Bonanza Groups on Facebook, or Instagram, or Reddit, or Anywhere when we signed up for the system. Both Buying and Selling.

Or a chance to follow on YouTube or TikTok or something, and share suggestions where we will get more engagement other than the site itself?
