I am another huge Gymboree fan. The key to shopping there to beat the high prices is to KNOW when the sales are coming. Their key sales are:
*Gymbucks ($25 off of a $50 purchase)
*Rise and Shine (usually 25% off a new line)
*Friends of Gymboree (between 25-30% off)
*Red Hot Dot Sale (past lines, deeply discounted)
And of course, if you have the Gymboree Visa, it is an additional 5% off.
