        Always happy with the product, but $96 shipping from New York to Ontario is a hard pill to swallow. Don’t think I’ll be ordering again until that changes.

        Supply Chain is terrible

        Even when you order in-stock items, Gfuel will charge you and then take 3 months to ship. This was never the case 5 years ago. I won’t be using Gfuel anymore, it seems the marketing has gone up but product availability is not up to standards. Not waiting three months for an order.

        Best sour flavor

        Hands down one of my favorite flavors. I got the collector box, burned through that and then ordered a second tub.
