On 4-10-17 I order a trampoline from staples online (I know, weird that staples carries trampolines). I purchased it for 379.99 and got a confirmation email. Last night I decided to email staples because I haven't received an email with shipment information on it. I get an email back this morning saying they cancelled my order because it is out of stock. I go to the staples website and look for the exact same item number and it is now 679.99 and says available online. Is there anything I can do about this or am I just SOL
