What products are worth it in 2026?

In Canada we have Tim Hortons, Tim Hortons runs a contest every year called roll up the rim. When you buy a coffee they have a spot on the rim of the coffee cup to roll up and you can win all sorts of prizes. I won a 40% discount code for Skullcandy and I don't know what to buy. Any suggestions? I have some older Indy Evo buds but they are on their way out.
