I buy Lego pieces from Bricklink probably at least once every few months and have been doing so for several years, so I have collected a massive freezer bag full of the little bags, and I don’t really do anything with them. Does anyone else have this problem, and do you use them for anything?
Your mileage may vary, you have to be careful when putting together a parts list - shipping cost will eat you alive pretty quick.
Ive also noticed the bigger sellers that have everything also have their prices way above average, so if you hit buy all with fewest stores youll overpay like its no ones business
If you put all the parts on a wishlist and then buy locally, the shipping cost will generally be only a few dollars each.
Also, I don’t really agree with the notion that bigger stores are more expensive, it really just depends on the store. Here in Canada there’s like three stores that are ludicrously expensive, and all the rest seem about the same.
