Where can I buy magnets online for my funky present?

[Scootergrrrl]

I've found a cool idea for the DC's to make their beloved daddy for Father's Day but I need some fairly solid plain magnets (ie not the paper-thin things). Where can I buy magnets online for shipping to a BFPO address?

If anyone's interested, the idea from a book called Making Stuff is to cover a baking tray in material then stick pretty buttons to magnets to make a magnet board for Daddy's office. It looks better in the book than it sounds here...

actually that sounds pretty easy/doable/and presentable. if you used nice fabric or something cool, like my 'its a beautiful day!' tea towel from pedlars
dunno hwere to get magnets tho... hobbycraft? ebay?

Thanks LL - we are on a BFPO and they are bound to sell them in Dunelm (don't tell me you haven't been there yet!). If I draw a blank online I'll send you on a mission .
