I bought these commercial migratory bottoms from a retiring bee keeper for $ 5.00 each, picked up 10. Spent the weekend modifying them to allow for a bottom entrance and the last picture shows how 2 hive boxes fit on pallet. I used reclaimed 1 x 8's to make all furring strips. Total invest per pallet less than $10.00 each. DSC01635a.jpgDSC01637a.jpgDSC01639a.jpg Thanks goes out to DC Honeybees for providing the plans in another thread.
