If that wasn't confusing enough for you, add this:

Below-90 players see something called "Special Offer", which, according to the above, actually is a Vintage Offer for 90+ players, but does not match what the 90+ players currently see as "Vintage Offer". In other words, even though the below-90 SO is a 90+ VO, the two are offered at different times.

In summary, at any one time, the game has three sets of offers active:
 * 90+ SO
 * 90+ VO
 * below-90 SO (which actually is a 90+ VO from a different week)

Confused yet? ;)
