Pick of the Litter items are a preorder item. During once the ordering period is closed, the items are produced over the following week. Because of this tight turnaround, it unfortunately isn't possible to to add late orders once the Pick of the Litter has been removed from teddythedog.com.
Sometimes we do produce extras of popular Pick of the Litter graphics and if we do, they'll typically be posted back on teddythedog.com about two weeks after the POTL's ship date. You can always view past POTL's ship dates here.
