1) Say No To Roses
Sure 12 Red Roses means love.  However, unless you've only been dating a short time or you know roses are her favorite just about any bouquet of flowers is perfect for the occasion.  Flower stores really increase the price of roses during valentine's day so just say NO to roses.  Simple as that.  Looking for other nice flowers?  Try Carnations or an assortment of flowers.

Suggested Flower Stores: Next Day Flowers, Clare Florist and Flying Flowers.

2) Buy A Smaller Box of GOOD chocolate.

Instead of spending a large amount of a box of chocolates go for quality NOT quantity.  Surely you don't want your girl eating a whole box of chocolates by herself anyway.  Why not get her 6 chocolates of her very favorite type.  Note that I'm not saying cheap out on chocolates.  I'm saying buy HIGH quality.

Suggested Good Chocolates Suppliers: Chocolate Trading Company and zChocolat.com

3) Lingerie Deals

Many lingerie stores have specials after Christmas and for Valentine's Day. Take a look around for special Lingerie Coupon codes, specials and promotions.  For example CheapSmells has a promotion for up to 80% off regular priced items right now.

Suggested Retailer:  Fig Leaves UK, LaSenza UK and CX LONDON BOUTIQUE

Buy and Prepare Early

To avoid paying extra for Flowers, shipping and chocolates you should prepare early.  In fact if you time it correctly you can get some Christmas Shopping sales and buy the products you need for Valentine's day.
