At 9 pm grid time (PT), the HUGE Merchant Sales event is scheduled to end across the OSFest grid BUT the grid remains open until the 31st so you may be able to continue shopping dependent upon the merchant.
We went shopping yesterday with HG avatars using the Merchant teleports to all of the merchant parcels and found some great items! Some were free, some were discounted and purchased with Gloebits, and others were purchased via Paypal. All were great buys! In case you missed it, here is the list of participating merchants below. See you in the grid!
