I bought my 16gb sd card for $30. delivered to my door. 16gb+8gb stock=24gb. Plenty IMO, as opposed to $100.+ for 32gb forget it, not worth it for the price...
I got the Sandisk 16GB card with USB reader from the Verizon online store. I'm sure that will hold me over for a little while. I've been filling my storage up with music files galore and some photos.
Plug in USB port connecting your computer and phone.
A screen will show on your Incredible titled Connect to PC. "Charge only" is selected by default. Instead, choose the third option labeled "Disk Drive"
Tap "Done" at the bottom.
Depending how your computer is set up, you may get two popup dialog boxes, or you will have to go to your Computer ("My Computer" pre-Vista) via Start Menu (or if the icon is on the desktop).
One will be your onboard storage (sized at roughly 7 gigabytes). The other is your SD card.
Remember to switch back to Charge only by dragging down the notifications window, tapping the mode that the phone is in while connected.
