However, fans who did not qualify within this window were able to log on and purchase.
This has meant they have been forced to null and void any purchase made today and launch a new sale tomorrow.
This has enraged fans, with the SFA blaming a technical error.

A statement reads: “The Scottish FA is aware of a technical error that occurred during this morning’s ticket sale for the upcoming FIFA World Cup Qualifying match against Denmark, which allowed purchase by some Scotland Supporters Club (SSC) members who were not eligible during the window that was reserved for those with 32-21 Points.
“As a result, we will regrettably need to restart the sales process from scratch in the interest of fairness, with any purchase that was made today being cancelled and refunded.
“The new sale will commence at 10am on Wednesday, 23 July.
“The SFA would like to apologise for any inconvenience caused to supporters.”
It comes after fans were already baffled at being given an allocation of just 1,740 tickets for the opening qualifier.
