Piping tips ??

Planning on making a birthday cake for a friend this weekend! What piping tips will I need to start? I’d rather go to the local store and buy a few for $2/each or a small set for $5 that are Wilton vs a crappy Amazon set!

I’m trying to go toward the design in the pic attached- chocolate cake, PB icing with some swirls on top with Reese’s, and I wanna pipe “happy birthday” on top! This is my first cake I’m making, and I’m just getting started so I wanna build my baking collection !

Also will accept any and all tips (& recipes!) for icing, cake and all! 🩷 TYIA!!
