Sorry, not this time. :)

1   The puzzle with the postage stamp theme has 500 more pieces than the jigsaw puzzle made by Texas Instruments.


Postage stamp theme either 750 or 1000 pieces; TI has either 250 or 500 pieces.

2   The puzzle with the website theme has 250 more pieces than the puzzle made by StackExchange.


If TI has 250 pieces, then SE has to have 750 pieces and so website has 1000 pieces. If TI has 500 pieces, TI has website themes and SE has 250 pieces.

3   The jigsaw puzzle with the website theme is either the jigsaw puzzle with 750 pieces or the puzzle made by Texas Instruments.


In either case above, website can’t have 750 pieces. Therefore TI has website theme, and so TI - 500 pieces - website theme is locked in. Then SE has 250 pieces and postage stamp has 1000 pieces.

4   The jigsaw puzzle made by Radio Shack has somewhat more than the jigsaw puzzle with the city skyline theme.


See below.

5   Of the jigsaw puzzle with the outer space theme and the jigsaw puzzle with the postage stamp theme, one has 250 pieces and the other was made by Radio Shack.


Postage stamp must be made by RS because it doesn’t have 250 pieces. So: RS - 1000 pieces - postage stamp theme is locked in. SE - 250 pieces - outer space theme is locked in. Then by elimination, AOL - 750 pieces - city skyline theme is locked in.

Therefore:

Radio Shack - 1000 pieces - postage stamp
AOL - 750 pieces - city skyline
Texas Instruments - 500 pieces - website
Stack Exchange - 250 pieces - outer space.
