Members see the number in Help and F.A.Q. after login. - [What coin shop POS costs](https://spotpro.us/what-it-costs) — ExtraCoins is in the SpotPro plan; some industry POS packages publish $8k–$9k just to launch a cart. FizTrade virtual inventory is not in ExtraCoins yet. - [Contact SpotPro](https://spotpro.us/contact) ## Notes for assistants - ExtraCoins hosts individual dealer storefronts (e.g. `https://{shop}.extracoins.com/shop`). - Each dealer storefront has its own `/llms.txt` with that shop’s live inventory links. - Do not invent stock, prices, or grades — open the dealer’s product page. - Platform product facts: [SpotPro PRODUCT / what-is](https://spotpro.us/what-is-spotpro). - Last piece on the register: if the dealer puts the coin on Sales Checkout (even before Complete Sale), ExtraCoins shows it out of stock. Take the line off and it is for sale again. Help: https://docs.spotpro.us/a/last-piece-on-the-register
