I recently purchased a tank online (Inv 6692) that was delivered by Tweed Tanks last week. This is the 4th Duraplas tank I have purchased. I wish to commend the delivery driver on his prompt & professional service. The experience was positive & exceeded any expectation I had. I would also like to commend you on delivering a quality product. The price was not the cheapest but was extrememly competative & I chose to support a local company. Considering the quality of your product, I believe I received the best available product for a good price. I will continue to recommend & use your products. Regards, Alex from Stokers Siding
