You might pop into Target or call your local store and see if they have hit either 50% off or 70% off for outdoor items. This varies considerably from store to store so no promises as to what you will find but my local store hit 50% off this weekend.
The furniture was discounted and then a lot of planters and gardening supplies and lights were also 50% off. The outdoor pillows seem to be just 15% off although I always suggesting scanning things to be certain.
I have not been to my store yet today but they seem to mark things down in seasonal sections on Sunday so you might get lucky today!
