I bought a lot of things from All Electronics in the past, but only use them for items I can’t find else where. The currency exchange, international shipping costs and time were the killers.
Both Mouser and Digi-Key will post both American and Canadian prices. The Canadian prices are often far less than the American prices with the currency exchange rate added. Both offer free shipping if the order is large enough. Mouser’s shipping is really fast.
But recently a friend suggested I try the Electronics Section in Amazon. Incredible! Components at a fraction of the price. But you have to know how to describe what you need. Typing in “Terminal Block” will bring up 356 pages. Typing in “Terminal Block, 5mm pitch” will only bring up 15 pages.
BTW: Cutting the new All Electronics straight trace perf boards is a challenge. Scoring and snapping almost impossible. So I bought an inexpensive plywood blade for my small and very portable chop saw. What a treat! Cuts them smoothly and only eliminates 1 trace.
