Ordering Information

We accept Cash, Money Orders, Credit Cards, Paypal, and Personal Checks.

The fastest way is to order with a Credit Card, or Paypal using our shopping cart. These orders usually ship in one business day. We accept MasterCard, VISA, American Express, and Discover. We use a sophisticated form of address verification for all credit transactions to protect both of us against fraud. If the billing address for the credit card does not match the shipping address for a customer, we hold the order for verbal, personal verification. Feel free to call us with any questions that you might have or if you just want to talk to a human to place the order.

Paypal will allow instant transfer of funds to us. Our Paypal account is: paypal@discount-hydro.com.

You must be a VERIFIED PAYPAL USER or we will NOT accept the transfer.

Personal checks are held up to three weeks for clearing.

Money Orders will usually ship the same day that we receive them (Please use U.S. Postal Service Money Orders)..

Cash orders will usually ship the same day. Note: Please send cash using a traceable form of delivery (FedEx, USPS Overnight or Certified Mail...)

If you are mailing in an order, please use our Cart system on the website to place the order. Use the "Money Order" checkout on the top of the cart page. You only need to enter your ZIP code for calculation of the shipping of the order. All other information is optional. At the end of the checkout procedure, you are presented with a printable order form which you can fill in any missing address information and send to us with payment. Our shopping cart will give you the shipping total when you enter your ZIP code.

On Cash, and Money Order Payments we DO NOT KEEP YOUR NAME OR ADDRESS. We send you back everything that you sent us (except the payment). We can ONLY reference your order by your ZIP code or by your Invoice Number. We are absolutely serious about confidentiality of our customers.

Shipping Information

We charge only what we are charged for shipping.

We ship VIA FedEx, U.P.S. or United States Postal Service Priority Mail. Many large, light items (rockwool, etc.) when shipped via FedEx and U.P.S. Air Services (Three Day, Second Day and Overnight) are charged by 'Dimensional Weight'. Due to this, we reserve the right to amend the shopping cart calculated shipping charges to actual charges. We will notify you if this situation occurs. It does not affect U.P.S. Ground Charges.
