Dripshipper products fulfill from our location, not from your own Shopify inventory. If that location is not available on the listing, Shopify grays the product out or a bundle will not sell.
Fix a grayed-out product
In Shopify, open the product.
Confirm it is assigned to the Dripshipper fulfillment service / location — not “Your store” only.
Do not set our inventory to 0 by hand. We treat connected SKUs as in stock.
Re-import or reconnect the product from Dripshipper if the SKU mapping broke.
Bundles
A bundle that mixes Dripshipper coffee with a mug (or any item from another location) often fails. Shopify cannot pull our coffee from one location and your mug from another in one line the way most bundle apps expect.
Sell the coffee as its own product, or use a bundle app that supports multiple fulfillment locations. See How do I connect Dripshipper with Shopify?
