These bulbs come from China, so surely you can buy them directly from someplace closer and save a ton on postage?

The trick is finding ones with the larger globes: 14 mm vs 11 mm.

For me, the link above is 50 for $7.99 free shipping. You probably want either the E10 1.5v 0.3A or E10 2.5v 0.3A (GE14).  These are the slightly smaller 11 mm diameter vs the 14 mm diameter from the link Bruce posted.

All the bulbs that I received in Jensen products were the smaller 11 mm size.
