Import Data from Web

Hello everyone,
I'm a fairly literate computer user who just got a project from a friend.

I have a list of Halloween Costumes with Product codes (3,200 Cells Long).
What I have to do is "copy" each Code One by One and "paste" it onto
the website to search. Then when the Costume comes up I have to "copy and paste"
the PRICE back to the spreadsheet.

My question is: is there anyway to do this easier??? Are there any aps or programs out there that can Import the Prices Directly from the site if I can give the codes.

Someone tried running me threw "Importing Data" in Excel but the website is too Flash dependent. ???

I'm really stuck here and have a time frame to uphold....any help would be greatly appreciated!
