Radio shack is so lame for cap's
By all means you can go in there and buy one.. maybe two 47uf @25v caps (radials) for like $1.27 each... 8-o
If you need to buy some caps, and going to the Mouser links is too complicated for you, then just ask questions in the appropriate thread for your Main Board, I am sure someone will help you.
Speaking of Mouser, they are located in texas, i'am located in michigan. I ordered my caps on dec 2nd, they shipped on the 3rd, I just got them today in the mail box (Dec 11th).
I feel it took way too long, USPS was used as the shipper and i selected the cheapest shipping price $5.99.
Now they are here I took some pictures so you can see how they come, my order was (100 - 10uf@50 Volts) and (100 - 47uf@16 Volts)
