I just returned from Everything Reptile in Chadds Ford, PA. I was trying to exchange two heat emiters for snakes that my granddaughter had bought yesterday. The policy is not to exchange those types of devices but she had just got it yesterday and discovered they did not provide the right temperature. The clerk said she should've done her research. So, I bought just one of the larger size. . Upon returning to my granddaughter's house with the 100 watt one and the two 60 that they would not exchange even though she had simply tried them out, I told her what the clerk had said. She said when she told the clerk what she wanted, he simply handed the two smaller ones to her and said they should do. So, she did not think she had to do any research since the store personnel recommended that size. It was never asked what size tank she had or what temperature she would like to maintain. I can understand the no return policy, but in that case, clerks should be trained to help the customer find the right product. read more
