UPDATE: The sale has been turned back on and is extended to last through 11:59pm PST on Sunday, February 19.
The Marketplace Rebate Sale was scheduled to last until 11:59pm PST tonight, February 18. Some issues arose with certain items having incorrect prices and others that weren't enabled for rebates being flagged as such, so it has been temporary disabled. Piestro gave this update on the official EverQuest II forums:
Unfortunately due to technical difficulties we've had to suspend the One-Day Sale. At this time we've disabled the sale and are working to remove any remaining sale notifications from the Marketplace. We will offer the same items on sale again at a future time so that anyone who wished to take advantage of the deal offered should still get to do so.
Thank you for your patience,
The Double Experience Weekend is unaffected and will continue to run through 11:59pm PST on Monday, February 20, 2012. Erollisi Day will also end at the same time, so get those last minute quests and purchases in!
