I'm doing a countdown to Spring with an Amazon Countdown Deal on my eBook, Indoor Salad: How to Grow Vegetables Indoors. So, if you haven't picked it up yet, on March 17th the price will be $0.99, then rising by $1.00 each day through March 20th, then back to normal March 21.
For UK folk, the Countdown Deal starts March 18th with a price of £0.99, stepping up to normal price on March 20th.
Great time to check it out! Includes lots of good tricks for starting your outdoor crops indoors.
