First and foremost there is actually no gymboree wholesale website site or anything like that.  People who resell Gymboree, including wholesale lots, obtain it all the same way.  Here's the scoop...

Why Gymboree is so popular....Gymboree puts out themed lines a few times each month.  All the items in these lines coordinate from head to toe to make ADORABLE outfits.  Popular items sell out fast and they soon become hot items on eBay as this is the only place people are able to find them. 

What sizes sell the best...From my experience, Girls clothing in size 2T-5 sells the best on eBay. Not to say that smaller sizes (under 12 months) and boys clothing don't sell, however, on average they just don't sell for as much as girls 2T-5 clothing does.

How to obtain Gymboree at wholesale prices...WATCH THE SALES...Let me repeat...WATCH THE SALES.  This is how people get Gymboree clothing for so cheap.  Gymboree will mark down older lines up to 60% off and often run sales at the same time that are good on regular AND sale priced items...Some of their popular sales like COF (Circle of Friends) gives an additional 30% off your entire purchase, also they have Red Hot Dot Sales (items sell for $2.99, $4.99 and so on), Gymbucks (Spend $50, get a coupon for $25.00 off your $50.00 purchase), etc.  Also, a Gymboree Visa automatically will give you 5% off your purchase.

Well that's pretty much it.  I appologize for all the people whom I upset for spilling the "secrets" for free, but I hate to see people spend money on a dumb e-book that pretty much tells you to watch the sales....

My advice for those starting out...

     *Start small...spend $50.00 to $100.00 and see what you get back in return after fees.  You can get a feel for eBay and see if you really like it without getting in over your head.  Be sure to ALWAYS include the name of the line in your listing header to maximize you selling potential.

     *Use CAUTION when purchasing Gymboree Wholesale lots....never buy a 50% off lot to resell... you will be lucky if you break even after fees.   These lots are great for clothing your own children, if you can get a size specific lot.

     *Sign up with a few Gymboree lover's sites, my favorite is Gymbohaven.  This is an AWESOME site.  They have line identification with pictures, newsletters that includes the latest Gymboree Gossip, and best of all it's free (a donation is always helpful though). 

     *HAVE FUN...if you don't love adorable kids clothing and love shopping then this probably isn't the thing for you....

Take Care and Good Luck!!!

P.S.  I have had a lot of questions from people asking about poly bag/packaged Gymboree and where that comes from.  Well, for those of you wondering...it's simply from Gymboree's website :-)
