Just received a `newsflash' e-mail from Ken Bromley www.artsupplies.co.uk who are offering Winsor & Newton watercolours (and Gouache) at 30% off. This makes 14ml Series 1 £7.21p (5ml £3.85p) to series 4 £11.41p (5ml 5.74p). 37 ml are similarly discounted as are half and full pans. Watercolour mediums are on offer at 35% off. This is about 5% more than Bromley's normal discounted prices. You have to buy 6 tubes or pans to get this offer and doing so also triggers a free half pan of Quinacridone Magenta. If this free pan offer attracts you then the overall price package would work out better but there is not a lot in it.
A look at current Jacksons www.jacksonsart.co.uk and Great Art prices www.greatart.co.uk indicate they are cheaper at basic prices! Series 1 14ml from Jacksons are £6.93p and Series 4 £10.89p!!! Great Art are very close to these prices. I suggest ALWAYS compare prices before thinking you have a bargain. With the price of art materials, particularly those for watercolour, my advice is shop around and compare prices as the situation is very volatile. It's tough out there for art suppliers but even tougher for many artists. I have also checked the 5ml sizes and a similar situation appears to exist.
There are other art suppliers. I have not checked any very recently as the ones above are usually at the forefront and all offer free carriage if purchases exceed £40. Some others appear to be becoming more competitive and I'll be having a look at one or two shortly.
