Shopify bundle products

It is possible to bundle multiple products under a single warranty. To do this you need to associate multiple products with a single warranty line item. Mulberry warranties on Shopify have properties in the cart line items and rely on setting the property "_variantId". Typically this would be set to the actual single Shopify product's variant ID.

For bundles you can set multiple product variant IDs in the format "_variantId": "bundle={variantId#1},{variantId#2},{...}". An example of this for two products with variant ids 1234 and 5678 would be "_variantId": "bundle=1234,5678".
