Possible YMMV, but Kroger family of stores has an online coupon available for $2.50 off any prepaid wireless card of Boost Mobile, Cricket and/or Verizon. There is no stated minimum purchase to get the discount, other than the requisite minimum offered on the providers cards. For Verizon the minimum notional value of a purchased card is only $10. Offer is available for in store purchase only, one per account, and coupon must be clipped to loyalty account prior to purchase. Coupon expires July 7, 2020.
