Save money, take your punctured tubes home and patch them after your ride.
Here is a quick tip on tube patches. The patches included with most kits work ok, but the patches are needlessly oversized for a road bike tube. Most the of the patches I have encountered are large enough to wrap around more than half the diameter of the tube - it can make getting them to stick difficult.
99% of my punctures have been very small, why not use a small patch? The best patch I have found so far are REMA F0 (16mm) patches. They work great. They are the best patches I have found thus far.
