Card rates below are general/no-bonus-category cash-equivalent rates (Costco.com purchases don't trigger travel/dining/gas
bonuses on most cards). These are best-known figures, not live-verified this session — check your card's current terms.
Pick "Custom" to type your own. CollectPure fee defaults to their published 0.75% Bullion Fee Rate — edit if selling
a different metal/product type (Silver/Platinum/Palladium is 1.00%, Numismatic is 1.5%).
"Refresh prices" fetches CollectPure's live bid + spot gold price, and Costco's price via r/CostcoPM's
automated price-alert bot (u/costco_pm_alerts) — all through a local proxy. Run
python refresh_server.py in this folder first (needed to work around CORS; see that file's
header for why). Reddit's RSS rate-limits hard, so the Costco figure is cached server-side for 10 minutes;
if it's unavailable the field is left for manual entry.

Premium % = (Costco price − CollectPure bid) / Costco price. Net margin % = Total rebate% − Premium% − CollectPure fee%.
Rebate tiers assume Costco Executive Membership's 2% annual reward (capped at $1,250/yr on $62,500 of qualifying
spend — paid later as a Costco Cash Card, not instant) stacked with a 1.5% / 2.0% / 2.5% cashback credit card.
Margins now include the CollectPure fee entered per row, but still exclude shipping/insurance to sell and sales tax
where applicable.
