We do understand the frustration with the ever-rising shipping prices.
Unfortunately, we cannot ship orders via envelope or First Class Mail.
We have had nothing but issues in the past when shipping envelopes and/or First Class Mail packages, which is why we only offer the Priority Mail option now.
We realize these postal costs are not ideal, but we are dedicated to offering all of our customers the fastest, most cost-efficient shipping options.
Please let us know if we can further assist.
