Gamemolding is cheaper if they have what you need.
$25 with the 20% off coupon will get you a complete slot cutter set from Harbor Freight. Spend the extra $5, you never know...
My only beef with t-molding.com, and this is VERY long standing, is that he/they sell it in 20 foot lengths. I've yet to encounter a cabinet that only needs 20 feet and everything I've redone typically needs 24-28. It's a built in upsell, IMO. My other gripe is that my last order was all chunked together in one plastic bag and showed up with scuffs and scratches. Once you get over your phobia of dings on fresh t-molding, it's fine. They're making money hand over fist but it's a fairly cheap expenditure to make a cabinet look nice so suck it up.
