ELC have an online exclusive offer at the moment with 20% off full price toys if you're spending £50 or more. At £50 you're also looking at free delivery, so that saves another £2.95. I think this would be particularly handy if you're looking for outdoor toys for the summer.
You don't need any special codes or coupons, simply choose what you want and pop it in your basket. Your total will automatically be calculated and your discounts automatically applied.
One thing to be mindful of is that if your total after the discount is applied comes to under £50, you will have to pay shipping. For example, I added a slide and a water table to my basket which came to £55, then the £11 discount was applied and my total came to £46, so shipping was added for £48.95.
I went back and added a bubble machine for £15, bringing my total to £70 minus £14 for the discount, and totalling £56 with free delivery. Obviously this means I'm spending more than I would have, but at least I'm getting another summery garden toy. It's only a bargain if you were going to buy them anyway!
