Groupon offers a $30 Shari's Berries Credit for $15. That's $15 off and the lowest price we could find, although we saw it for $3 less last week. This voucher can be applied toward shipping, which starts at $9.99. Credit must be redeemed before June 30.
Of note, a $40 Shari's Berries Credit is also available for $20. That's $20 off and another price low.
