1.
Check out Ebay. Ebay has a vast amount of My Little Ponies,
www.ebay.com. This is probably
the largest grouping of My Little Pony available Search under My Little
Pony or MLP for starters. There are also other smaller
auction groups that sell ponies as well.
2.
Check out other MLP collector's sale and trade pages. You might
be surprised what you find.
3.
Check out message boards as well. This is where you link up with a
lot of people in the pony community and can keep an ear out for what's
going on.
3.
Unload those 80's toys you have to other collectors. For example,
trade Barbies for ponies. Trading is usually good business for pony
collector's. You'd be surprised about what other things pony collectors
like to collect as well.
4.
Yard/garage sales.
5.
Antique and collectible shops. Sometimes you run into badly overpriced
items here though. :(
6.
Thrift Shops.
7.
Word of mouth. I've gotten one or two ponies from people that I know
who found them at yard sales.
8.
Decide what conditions you will expect your ponies to be in.
Sometimes tail-less ponies can easily have their tails replaced with
other ponies tails, but you may not want to shell out a lot of cash
for mane-less ponies if you cannot replug. Be very careful with
the color match; it's often hard to get a straight match.
Good
luck with collecting.
