Well I can say I was a little hesitant to take back my dead mums to the store. I had bought them just last month. They were a lovely orange color and they both took a turn for the worse and became brown, dead dry brown.
I had heard that Lowe's had a return policy on plants, but was too embarrassed to tote my two dead mums to the store. I was not sure if they would take them back since they are annuals and not a plant (bush or tree). I called to check and to my surprise I was told, bring them in along with your receipt for a full refund. I did just that and the store clerk gave me my money back, which I used to purchase two new mums, this time in a lovely burgundy color.
