Yes They do
The GRID does carry a variety of computer cords and cables. For power supplies, they only carry the original manufacturer units. They are more expensive than some low quality knock-offs, but they're usually a third of what you'd pay for the OEM unit on Amazon or Ebay. Other cords and cables, such as ethernet or VGA, etc., are all inexpensive, and they guarantee the product.
They do have cords, but I would check on line for a cheaper or better deal
Yes they do have certain cables but they're probably cheaper on amazon.
