At 80% off, I'd consider buying all three. Even if they don't have an upgrade sale right away, at least you'd have them at a good price. You'll be farming the 4 lapper soon, and you'll still have a decent amount of gold left, and you can at least get the R$ upgrades going. It really depends on your goals though.
