I go to your store and want to get into the first Group Pricing ...

What do I do? Do I call you or do I buy a Product, that "looks" like an upgrade to the First Level Group Pricing?

I have been added to the First Level Group Pricing ...

I want to get Upgraded to the next level ...

What do I do? Do I call you or do I buy a Product, that "looks" like an upgrade to the Second Level Group Pricing?

Is this "upgrade", if a Product that "looks" like an "upgrade" the same Product or a different Product?

NOTE: pretend I have never ever seen your site and haven't a clue how you have it setup nor what it looks like to the customer ...
