Script which gives a landmark when item is purchased

I have seen, and used, a number of scripts which provide a landmark when a prim is touched. However, I cannot find a script which provides a landmark when an item is purchased. The script(s) which do that obviously exist but I can't find them! Do I need to buy scripts which do that from a script writer?

Thanks!

You could always place the LM inside the box of the purchased item.

Or, if you're using a script to sell your items, place the "Landmark" give into the script.

Yes, the best way would be to include a LM inside. Less spammy... otherwise it can be done with the 'changed' event...but i don't really see the purpose in this case.
