Thanks for your reply Joe, but that's not exactly what I was looking for. I think I'm getting closer though.

In design view I created a separate unbound Text box the same size as the Purchase date, Item Description, Quantity, Price, Extended Price combined, and set the property to "Can Grow" and set the border to "Transparent", Then I took the Purchase date, Item Description, Quantity, Price, Extended Price text boxes and also set them to "Can Grow" and made their borders "Transparent". Next I placed the new text box over top of the Purchase date, Item Description, Quantity, Price, Extended Price text boxes and "Sent it to Back". Then I placed a "Horizontal line" over the top of the text boxes in the "Detail section", and a "Horizontal line" above the "Tax" and "Total" (also making their borders "Transparent")  in the "Report footer", scrunched it all together and VOILA it worked (with the exception of the "Vertical lines" not being able to "Grow"), but I can live with this. See screenshot

It looks nice. It always feels good to find a solution that works for you.
