There are a lot of great resources and tools out there, whether your focus is on collecting as a hobby or selling to make money. Below are a few resources and products I personally use and generally recommend.

Apps/Services
whuppit
I built this one, so yes, I have a discount code. :) Use code “ECAS15” to get 15% off your subscription for life.
This isn’t a surprise if you’ve followed along. I built whuppit for myself and eventually opened it up as a service.
Nowadays it’s where I track all sales and purchases, it generates my eBay listings, I use it to track grading targets, I use it to track buyers and sellers, share inventory with potential buyers, run reports of all kinds, and negotiate bulk purchases.
Even if no one else were to use it, it’s too invaluable now for how I handle my business—I’d have to keep it running even if I was the only user.
Market Movers
You can get a 14-day free trial and 20% off for life using the code “EVERYCARD” on the link above.
Friends don’t let friends use eBay’s sold items page.
I love Market Movers for helping me see how different cards are trending, helping me determine if I want to buy particular singles and at what price, when I might want to consider selling one of those cards I’ve been sitting on, which cards I might want to consider grading, and more. whuppit, Market Movers and Discord stay open all day, every day.
I’ve been trying CardLadder as well, and I think the comps there are a little more comprehensive, but so far I think the actual features and user ergonomics on Market Movers feel a lot more intuitive and powerful so if I’m picking one, I’m sticking with this.
Gixen
Gixen was an absolute game-changer for me. It’s an eBay sniping service, and literally the moment I started using it, I started winning more auctions. I had to quickly dial back how many I was bidding on!
I personally use the paid version—at $7 a year it’s frankly underpriced. The sniping feature not only helps me win more auctions, but it removes a lot of the emotion that could otherwise cause me to overbid on something in the heat of the moment.
Sure, it looks like something built in the 1990s. But it’s reliable, affordable, and works so well. Huge fan of the product.
Selling Groups
BucketCardzLLC
Affiliate link provided saves you 20% per month.
This is my favorite selling platform, over all other Discords, eBay, social networks, etc. Anything with a comp moves very quickly, and I’ve built up a number of strong relationships with buyers now to the point that I know I can sell through most grading orders in a couple of days.
Like any Discord group, it can feel a little chaotic when you first get started, but if you’re hoping to increase how quickly you can move inventory, this is the single best investment you can make.
Clymb
Affiliate link. I…honestly don’t know what I get back? But it’s only $4.99 a month so it’s a pretty painless monthly fee.
It’s good to have options and while I don’t sell as much here as I do in Bucket’s Discord, I’ve made enough deals for me to find it’s very worthwhile, particular given the very low monthly cost.
The Collector’s Keep
Formerly Bob’s Card Market. To be honest, I don’t move much here. But I do really like the community and find the conversations interesting, and they owners/admins have always been very kind and supportive. Plus it’s free.
