Most games don't need a custom insert
Custom laser-cut inserts are great, but they're overkill for a lot of games — and they add up fast across a collection. For most boxes, the goal is simply to keep component types separated so setup is fast and nothing gets lost. A handful of cheap, repurposed, or DIY solutions do that job for a fraction of the cost, and you can save the fancy inserts for the heavy games you play most.

Cheap fixes that just work
The board game community leans on a rotating set of budget staples, most of them from craft, hardware, and dollar stores rather than the game aisle.
- Small clear plastic tubs bought in bulk: hand each player their own little box of pieces and pop open shared resource tubs — clear so you can identify contents without opening.
- Tackle, bead, and craft compartment boxes: look for adjustable dividers so you can size each slot to the components, and rounded bottoms for easy scooping.
- Seven-day pill organizers and condiment cups: cheap, ready-made compartments for small tokens.
- Silicone cupcake liners: soft, reusable, and easy to color-match to component colors as pass-around bits bowls.
- Small photo or craft cases (4x6): ideal for card games, one game per case, then corral several in a larger tray so they stand together.

Upgrade the baggies before you replace them
If you're going to use bags at all, don't use the flimsy ones the game shipped in — they tear when every player handles them and are fiddly to reseal. Heavier-gauge resealable bags (the thicker 2 mil and up) are easier to open and close and hold up far longer, which makes them genuinely good for player-specific pieces. Mesh zipper pouches are another flexible option that comes in a range of sizes and colors, and drawstring cloth bags are nicer to handle than plastic for shared resources. Bags are still the cheapest fix; just spend a little to get ones that last.

If you repack a game, plan the labels
The moment you move a game out of its original box and into tubs or bags, you lose the spine and cover art you used to spot and grab it on the shelf. That's the hidden cost of repacking, and it's worth solving before you commit. A cheap trick is to cut a piece of the original box and drop it into or onto the new container as a label — though a flat cut-out isn't visible if you store containers spine-out, so plan for how you shelve them. Using uniform clear containers helps too, since you can just see the contents, and matched box sizes stack more cleanly.

DIY foamcore, if you like the project
For people who enjoy the build, DIY foamcore inserts are the budget way to get a fitted insert. Foamcore board is cheap, and you cut trays to your exact component count — including expansions — for a fraction of a laser-cut kit's cost. It takes time and a sharp blade, and it's worth it mainly for games you play often and want a clean, custom result without paying custom prices. There are plenty of community templates to follow per game.
The one cheap upgrade worth buying
If you buy just one organizing product, make it an adjustable-divider organizer box. It's inexpensive, moves between games as your collection changes, and turns a baggie mess into sorted, liftable trays. It doesn't lock components in place like a fitted insert, but for sorting tokens and cards it does the job for a few dollars per game — the best value per dollar in board game organization, and the natural step up from baggies.
When to stop DIYing and buy a real insert
Budget fixes have limits. For a heavy game you play constantly, with fiddly setup and lots of component types, a fitted foamcore or laser-cut insert genuinely saves time every session and protects the components for vertical storage. The smart approach is to start cheap on everything, then upgrade only the keepers — the few games that earn a custom insert by how often they hit the table.
