Since you described this as your first Perl program, let me comment on your loop. The others have given good advice for the data structures, so I'll just make a quick suggestion about your actual code.

You have:

$n == 0;
for (loop condition){
  $n++
}

• Use = for assignment, == for testing. This line doesn't actually do anything, except cause a warning. It tests whether $n (an undefined value) is equal to zero.
• On the subject of warnings, you are running with warnings enabled, right? <nobr>#!/usr/bin/perl -w</nobr> at the top of your script will enable many useful warnings. Don't leave home without it. :-)
• On the subject of global variables ($n is a global, in your code), don't use them. Adam has <nobr>use strict; #Always</nobr> in his code. This is a good idea. It will help you avoid problems.
• Looping: Here is a slightly more idiomatic way to do your loop:

for my $Idx (0 .. $#combo){
  print "SKUID:$skuid[$Idx]\n";
  print "NAME:$name[$Idx]\n";
  print "PRICE:$price[$Idx]\n";
}

In other words, for each index in @combo (the 0 .. $#combo part), set $Idx to that index and run the body of the block. This accomplishes the same thing as your code, but doesn't leave an unused variable ($n) lying around. It specifically uses the index of each element in @combo, which makes the code easier to follow and maintain. Besides, it looks so much cooler... ;-)
