Buying resources, materials, or goods in Imperialism and Imperialism 2 is done at the end of a turn during the series of screens that appear straight after "End turn" is clicked and before the new turn starts. Procedures in Trade Empires differ.
To set up an offer to buy anything, for action during that process, before the end of turn you click the third button in the main menu (with the "$" sign, called "Give Trade Orders") then the left-hand tab in the "Orders" column. You may offer to buy anything listed, up to your current maximum number of items in any turn.
You may arrange for particular nations to be unable to offer you anything if you impose a boycott, which works for both buying and selling.
After clicking "End Turn", when the program has done your selling, your resulting cash balance will show at top left (giving you a rough guide to how much you should restrain your buying if you will be in debt) and you will receive other nations' selling offers (if any). You get presented with one offer after another and may accept the whole offer (if enough merchant marine space is available) or a lesser number or may reject the deal. Offers follow the order of items on the standard list.
Finally you see the "Deal Book" for details of what you bought and sold and some of the other factors affecting your cash flow. Turn the page at the bottom in the usual way if there's an indication of a subsequent page. You may re-inspect the Deal Book later in the turn from the "Help" menu reached from the information button at top right of the map screen.
