We pulled the top questions our support inbox sees every week and answered them here. Save this page before you start checkout so you have it handy.

Can I combine coupons?

Only one discount code can be active per order. If a bundle already includes a discount, the cart will politely reject additional codes.

How do I change my shipping address?

If the order is still in the cart, edit it before you hit checkout. Once placed, email gsgmfg@proton.me within 12 hours and we’ll attempt an update before fulfillment prints a label.

What happens after payment?

You’ll get an order confirmation from orders@gsgmfg.com within a few minutes (check spam/promotions if it’s missing). When the package is ready to hand off to the carrier, tracking will come from ship@gsgmfg.com.

Still stuck?

Reach out and include:

• Order number (or the email you used).
• What you were trying to buy.
• Screenshots of any error messages.

That let us answer in minutes instead of asking follow-ups.
