Know what you have before you sell it

Resources & Guides

Free knowledge to help you spot what's worth money — and a team ready to turn it into cash.

Welcome to The Toy Showroom's resource hub: a free, no-strings knowledge base built for finders, resellers, and everyday people who want to know what's actually worth selling. Whether you're sourcing at yard sales or clearing out a closet, our guides help you recognize the good stuff before it slips by. And when you find it, remember — we'll buy it from you outright or sell it for you, so you never have to deal with the hassle yourself.

Quick Answers

What kinds of things do you buy and sell?

Toys and collectibles are our heart, but we handle far more — electronics, brand-name goods, vintage finds, estate items, and the kind of overlooked treasures people don't realize have real value. If you're not sure whether something is worth money, that is exactly what we are here for — call or text us and ask. When you are ready for a real valuation, start your sell intake and add the photos there, and our team researches what your items have actually sold for.

What's the difference between a cash buyout and consignment?

With an outright cash buyout, you submit photos for a free evaluation at sell.kalijdesign.com/sell; once you accept our offer, we arrange your drop-off and pay you at drop-off after checking the items — no listing, no selling, done. With consignment, we sell your item for you across our channels and you collect a share of the proceeds. Buyout is fastest; consignment usually earns you more on the right items. We'll happily walk you through which makes sense for what you've got.

How does the 60% consignment split work?

It's simple: when your item sells, you keep 60% of the net proceeds and we keep 40% for handling everything. That "everything" is the whole job — professional photography, listing, pricing, answering buyer questions, shipping, returns, and chargeback protection — across eBay, Amazon, Walmart, Poshmark, Depop, Mercari, Whatnot live sales, our weekly online auctions, and the Upland Toy Showroom floor.

How do I get started?

Submit photos of your items for a free evaluation at sell.kalijdesign.com/sell, or reach out with questions and we'll guide you from there. A clear photo is often all we need to give you a ballpark and tell you whether cash or consignment is the better path.

Do I have to come in person?

Not to get an offer. The evaluation happens online — submit photos at sell.kalijdesign.com/sell and get a sense of your item's value without leaving home. You come to our Upland showroom only after you accept an offer or consignment terms, for a drop-off we arrange with you.


Selling it yourself means buyer questions, flakes, no-shows, lowballers, listings, photos, shipping, returns, and chargebacks. Let us handle all of it. Submit photos for a free evaluation at sell.kalijdesign.com/sell, then choose a cash offer or consignment.

You found it. Let us sell it.

Skip the listings, lowballers, flakes and shipping. Submit photos for a free evaluation — take a cash offer, paid at drop-off once you accept, or consign it and earn 60% of the net while we do all the work.
