How to Buy a Slot on CrowdSpark (Email Sign-In, No Password)

Pick a slot

Browse the grid or open any /slot/[n] page. Open slots and owned slots both show the exact price on the button.

What it costs

Open slots are $5. Owned slots follow 1.25× rounded up with a +$1 floor: $5 → $7 → $9 → $12 → $15.

Sign in with an email link

You must be signed in before checkout. Enter your email, open the one-time link we send (it expires in 15 minutes), and you are in. No password.

The 10-minute lock

Starting checkout locks that slot for 10 minutes. Finish paying in time and it is yours. If the lock expires and someone else gets the slot before your payment lands, we refund your card automatically.

Paying with Stripe

Card checkout runs on Stripe. We never see your full card number.

Using credit at checkout

If you have site credit (for example after being taken over), it applies before the card. If credit covers the whole price, no card charge is made.

What to check before you pay

• The live price on the button
• Your name, link, and note (you can edit later while you still own the slot)
• That you are signed in as the right email
• Account limits: up to 5 slots, one open checkout at a time
