If you sell any of my products, I'll give you a large 40% commission.

Seeing as we'd both benefit, I wouldn't consider there to be any catches. Perhaps keep in mind the minimum payout and lead time (i.e. no commission until 3 months from the date of sale, otherwise the customer could ask for a refund, which would result in no commission for that sale).
You can read the full terms.
