When you bundle products there are a few things to keep in mind:
Include best selling products, as well as complementary products and products that build the best long-term customers (use Repeat Customer Insights to check which those are).
Set the price above your Average Order Value to help to pull up your overall AOV.
Start with 2-3 different bundles and every 60-90 days replace the lowest performing bundle with a fresh one.
Consider "launching" each new bundle to your existing customers to attract their attention and interest.
Bundling products can be a very rich product strategy but like everything else, it requires some experimentation and idea testing. Sometimes you'll win by following everyone's advice, other times you'll only win by breaking every rule out there.
But keep experimenting.
