Fedex is similar but perhaps not quite as greedy as UPS. With a little planning & patience, USPS is the way to go provided the seller will do it that way for you.

What drives me insane is that my friend is a border agent and they watch UPS come in with a stack of shipments and they stamp these papers @ about 2 per second. Each stamp is that $50 charge. I need to get into that business!! LOL

We ship USPS express only for international shipments (outside USA)

yup min chard was 35, and once your over a set amount then it is a persentage of the value.

I was talking to a guy who does canada post boarder clearance.. they charge 5 bucks for the clearance, and they only charge duty on items over 100 bucks and that is a randome thing also. not everyone will pay duity which explains why some stuff I ordered for my truck had duty assigned and some didn't.

I have my LEDs so now im trying to get everything togather. Iv looked at alot of builds and wondered what the best route is on attaching the leds to the heatsink. Some of the threads had screws and some didnt. Could someone let me know what is best. And if I should screw what type of screws should I be using? We dont mind drilling and tapping if thats the way to go. I didnt know what the difference is. Also (sorry for all the questions) I should buy
20g wire? And Flux core solder? I just wanted to double check. Thanks again for any advice.

Tapping and screws allow you to move them later but it's alot of work. Easiest is adhesive pads.

22awg is easiest to work with.

Thanks Milad. Ill go grabe the 22awg now. I think Ill try the screws on the smaller light and if it goes ok them Ill use them on the biocube. That way if I need to replace an led I can. If its a total pain Ill use the tape on the biocube.

Just make sure the screws don't touch the solder pads. Also always do a diode test on all the LEDs once everything is mounted before you power them just to check nothing is shorting on the heatsink.
