Giveaway Box: Buy‑to‑Enter

Run a giveaway where every paid order earns entries, then draw a winner you can check again.

Pick a prize, dates, and how orders earn entries: per paid order or per unit spent. Paid orders add entries on their own, guests included, and refunds and cancellations take them back. A line on product pages shows the entries. Logged-in customers enter once without buying, earn bonus and referral entries, see their own entries; mail-in by ID; a winner notice. When it ends, draw a winner weighted by entries; the seed and an entries fingerprint are saved. No theme edits: it's an app embed.
