Question about Titan WTL 4 (black, 40 - 85", max. 50 kg, swivelling and inclinable)

About 3 weeks ago I had already ordered this wall mount for the TV in the bedroom. Now I want another one and I noticed that the price has gone up from 119.- at the time to 139.-. Is this true or have I made a mistake about the product? (1 x Titan WTL 4 (Black, 40 - 85'', max. 50 kg, swivel and tilt, wall 5339322)
