Due to overcrowding and lack of bloom, I dug a row of my daffodils. There are 4 different varieties of which I kept separate as I dug (I had placed a division marker between each variety). I will pack several bulbs in a USPS flat rate bubble mailer. My guess is at least 40 bulbs will fit, 10 of each variety. NOTE: that these bulbs have not been washed. They are smaller than bulbs sold on the market due to overcrowding and I'm not sure how many will actually bloom in spring.
Cost for the USPS flat rate bubble mailer is $5.75. If you choose to pay through PayPal, it would be $6.40 for me to cover PayPal fees.
Here's a couple I'm pretty sure are in the row:
