Stripe is closing card processing accounts on Shopify stores selling restricted items. You cannot sell anything that is toxic or flammable - so no cleansers, no aerosol sprays, no lithium batteries, no research chemicals and no Peptides. It is up to Stripe to determine if your products are on the list. Here is the list:

If you sell any of these items then find another processor as you will only have a 4 day notice before they close your processing.
