I just purchased the HP 96 & 97 Cobmo Pack online (Order #5141638394472). I drove to the Walmart to pick up the items. Even though the walmart website said that the Combo Packs for the HP96/97 Cartridges were in stock and available, that Walmart does not have the Combo pack.
Since I ordered it with the office Credit Card, I did not bring the card with me and had to come back to the office, cancel the order and re-order the Cartridges individually. That particular walmart did sell the HP 96 & HP 97 Cartridges individually. There were dozens of each cartridge on the shelf.
I do not have physical possession of the office Amex since my brother is not in the office today. When I attempted to just re-order the HP 96 and HP 97 Cartridges individually, the walmart system says that I can't order the cartridges online. It says that no walmarts within 50 miles of 77002 (downtown Houston) have those particular cartridges in stock. Even worse, I can order them to ship since the system is telling me that those particular cartridges are not available to ship.
