ATTQOTD: I use The Feed all the time, both to try samples and to buy in bulk (most of the gels I like aren't available in stores). They have really good customer service and shipping is free and pretty quick. Definitely get a discount - they're currently doing a 25% off sale, and some of their athletes have codes for your first order (SWAP should work I think).
You didn't exactly ask

but favorite higher-carb gels:
- Enervit Mango
- Victus Berry & Hibiscus, Watermelon
- Precision
- Carbs Fuel (I don't love the flavor, but it's $2 per 50g gel, so...)
Also a big fan of Skratch, which has a milder flavor than some other hydration products (looking at you, LiquidIV!

)
