Shipping InformationShipping Information I can ship seeds first class or ground advantage USPS in a protected bubble mailer with tracking numbers provided for 4.00 for unlimited amounts of seed packs. This is a safe secure way to ship with reliable tracking. I'm now also offering standard envelope shipping on seeds due to the rising costs. This type is regular standard envelope mail with 20$ of insurance and limited tracking. The rate is .68 for the first pack and .50 cents for additional packs. Note: this type of shipping may be rough on fragile seeds due to x-ray and lack of padding for protection, buyer assumes all risk. Many times, for standard envelope, USPS does not update the tracking or scan the envelopes. If your package takes longer than two weeks, please let me know. I am happy to offer combined shipping, and you will never pay more than 4.00 depending on the service you choose for combined seed order. Feel free to message me if you have any questions. Thanks for looking and happy gardening!
