**3 FOR 2** - WHITE DULUX TRADE EMULSION. R.R.P £35 EACH ?

We have 3 x 10L of Dulux White Trade emulsion, purchased recently from B&Q at a cost of 35 per 10L. Not been opened. No longer needed, but B&Q will not take back as we have lost the receipt. At 70 you are getting a bargain at 3 FOR 2 for quality paint. Thanks
