The difference between deluxe and standard

[combat medic]

I've visited the IK website but the product description for T-racks 3 standard seems to be the same as deluxe. What exactly is the difference?

The modules included. Standard has the 4 classic T-Racks Singles (The yellow ones) While Deluxe has the newer ones except the Black 76 and White 2A which are add ons.
