I bought a platinum theme deck for £11.95. And they are offering me £1.50, should I take that or ask for a little more.
Its all up to you my friend 
Depending on what you want in the first place. A sealed product or to open it.
A sealed product. Do you think £2.50 is fair. I just need a opinion.
I dont collect sealed product so im not an expert in this but if i were to buy a sealed product i expect it to be sealed or i will return the item for a full refund.
yea i was going to say, send it back and get your money.make sure they pay all your postage etc
This isnt a sealed product sooo what would you do with it if you take the 2.50?
If its for a sealed collection, send it back ^
