Update by user Jun 03, 2021 Repeated emails to vendor neither acknowledged nor answered. Not even sure whether Nature Hills Nursery received my complaint. Matter remains unresolved and I believe I have a valid credit of $90 with that nursery. Do not understand why they will not accept this credit. Original review posted by user May 04, 2021 I just tried placing order using credit of $90 (1BT6-WNSO 8738). I entered this credit as Discount and your response was discount not accepted. Ive spent a significant sum with you for past orders and expect this credit to be honored. Thank you. R Ballard
