First post so please excuse missing details.
T&N has a 20% off promotion on Amazon for their mattresses – I was within my 100 day trial for the mattress (purchased directly from them) and told them I would rather have them give my a refund than return it and then rebuy it from Amazon and they applied the difference towards my refund.
