The further you get into an album, the more doubles you pile up. It's just math: the first stickers are easy, the last ones are the ones that never come out. Those doubles stacking up are worth more than you think.
1. Swap them (the smartest move)
One of your doubles is someone else's missing sticker. Swapping is the cheapest way to finish your album: you don't spend, you just move what you've got spare. Cross your list with other collectors' and put together the best deal you can.
2. Sell them
Shiny and special doubles are in demand. You can list them with a price and stock for whoever's looking. Common ones are worth little one by one, but they move in bulk or by request.
3. Complete the album with friends or family
If two people work on the same album together, one person's doubles cover the other's missing stickers almost on their own. Sharing the collection means you both move twice as fast.
4. Give them away to get someone hooked
A handful of doubles is the best gift to get a kid (or a grown-up) started on their album. That's how half a collector is born.
5. Keep them sorted, not in a bag
If you pile them up with no order, they're useless for swapping because you can never find the one the other person asks for. Having them counted and listed (better if it's digital) is what makes them useful.
On Figuritas Online your doubles count themselves as you mark up the album, and they're ready to swap, sell or share. No keeping track by hand.
