I ran out of my supply of small bubble pack envelopes after about 10 years. Best deal for me was to buy another lot of 500, which will probably last longer than I will .

If you need a few, I can send you some at my cost plus standard postage:

1 pound (35) size 000 with self adhesive strip: $10

2 pounds (70) size 000 with self adhesive strip: $15

These are Hefty brand, the ones I've always used. If you live closer to Oregon than New York, I can probably save you another $2-3; I'd need your zip to check.

Personal PayPal with cash funding works for me.
