Via select Alexa-enabled devices and for Prime members only, Amazon offers the Elmer's Washable School Glue Sticks 30-Pack for $3.74 with free shipping. (This link is provided for reference only. To order, say, "Alexa, order Elmer's washable glue sticks.") That's $4 below our mention from last month and the lowest price we've seen. (It's also about $5 less than you could expect to pay at local stores for this quantity.) It is non-toxic and acid-free and is formulated to wash out of hands and clothing.
