Is there a way to undo a Bulk Attribute Update? I accidentally did a Bulk update to all of the prices for all of my products via admin. I went to Manage Products and ticked Select All thinking it was just the products on page 1 but it ended up being all my of 8742 products. I went to Update Attributes and changed the Price, Special Price and Tax Class. Now all of my product are all the same price which is wrong. Can I undo this change?
