The system is asking for a review of the product 14 days after they fulfilled it. Sorry, but it took 14 days before the product even arrived at my doorstep. I can’t give any feedback about the product. CWT’s cheapest, _paid_ shipping option has taken 7x longer to arrive than their competitor’s _free_ shipping. I had wanted to support a Canadian company, but this company’s shipping timeline truly sucked. I’m hesitant to give them a second chance.
Good day, Angela. We apologize for the lengthy shipping time and appreciate your feedback, which will help us identify which courier company to use in the future for shipments from Ontario to Alberta.
