Advice needed - Import Taxes

I have a buddy in Colombia who is trying to get a new PC… building it him self or prebuilt at this point is fine, but hes running into Import Tax issues… is there anyway to make these cheaper? hes a college student who specialized in Video Game Graphics.

Gorkie only way would be to have a lower price on the bill and shipping totals. However the customs reserve the right to appraise the value of the shippment.
