Its the age old joke...buy your kid a 100 dollar toy and they will like the box that it came in BETTER!!!
My two year old just likes whatever WE are playing with. A rubber ball, plastic disposible drinking cup, or even an empty paper towel roll (Ive taught her to say "Ricola" in it!!! Its hilarious!!!)
It all depends on your kiddo. Walmart has plenty of five dollar toys that can then be turned into games and such. My DD actually likes the plastic golf clubs they sell.
Another thought to your question is crayons. Does he like to draw on paper? I bought a cheapy pack of tablet paper at The Dollar Store and let her draw. However, dont skimp on the Crayons...get Crayola Crayon WASHABLES!!! They wipe right off of walls, tables and whatever else your Rembrant may see as a work of art!!!
I have taken an empty Pampers box, tied one of my husband belts on the handle and convinced her to pick up stray toys throughout the house...talk about killin' two birds with one stone!!! Picking up toys can be fun!?! Who knew?
