Note: please read the comments or notes below, you may be able to pick one up for as little as $10 C&C

Starlink: Battle for Atlas Starter Pack (Includes Game, Controller Stand, and Merchandise) $9.95 + Delivery from The Gamesmen.

Not as cheap as the $5 deals that have been around, but this is the cheapest one I can find atm.

If you missed out on those deal you may want to look into this (but take delivery into account which is around $9 unless you can pick it up in store).

Especially since the game is old now, and the physical copy with merchandise will probably become less available as stores run out of stock (I can't imagine shops buying more stock to sell at $5 because there wouldn't be any profit in it).
