similar items from different merchants should not be an issue --
duplicate offers from the same merchant would be an issue.

however, local, freight, or similar goods are not allowed --
items must have a fixed-priced and must be shippable
using direct-to-consumer shipping methods; and must
be shippable throughout the registered target-country.

also, regardless of shipping requirements, such items
require an exemption from global-trade data by google
before such handcrafted items can be listed.
