With 2-3 gallons, the most important thing is going to be a heater, not a filter.
Bare minimum, you will want the tank, heater, water conditioner and food (make sure the food is designed for Bettas. They don't do well on typical tropical fish feed)
Some 'extras' you probably want are a hood with a light and a filter. After that you want decorations and hiding places for your betta. Something at the bottom looks nice: rocks, gravel, glass gems, etc etc. They also have tons of decorations at just about all fish/pet stores)
But yeah, if you are looking for a kit, just go to the pet store and say "I'm looking for an aquarium starter kit that is 2 or more gallons and comes with at least a heater. They should be able to help you from there. However, be carefully about trusting everything they say on the care of your Betta. Some of them are somewhat misinformed.
