Hi, I'm very keen on these and been collecting them for years, now have 50 in various sizes and colours. Michelle is right, it does all depend on size and colour, some of the larger ones or those in less common colours such as lemon, orange, white are going up in price, £20 being the highest I've seen, but the general trend does seem to be upwards, albeit slowly. Yours is quite a large one and although a common colour it would probably do a bit better than 99p but not much more than you paid for it. I know there are many that do not agree with me, but I think these vases are just great and look particulary good arranged in groups. At the moment it's very affordable to build up a good display quite quickly. I say, "good choice" and if you like them keep buying! Cheers, Gill
