What is the website where we can buy bitcoins and cryptocurrencies at the LOWEST PRICES using credit/debit cards?

There's nothing like "Cheapest" or "lowest" price especially if you are dealing with a reputable exchange with good trading volume and crypto in general. Bitcoin and other crypto prices are always changing so "Cheap" or "expensive" doesn't really have meaning here.

For example last year $10K per Bitcoin seemed "expensive" but today when Bitcoin is $45K+ suddenly $10 is so cheap per BTC. I hope you are getting my point.

There are so many exchanges that offer the option to buy through credit card such as Binance, coinbase, coinmama etc

Usually, the price of Bitcoin between one exchange and another will not be far apart.
Maybe just a few cents or dollars.
In fact, what is strange is if you accept an offer (for example with P2P or individual transactions) and you get a low Bitcoin price offer and are quite as far apart as the $ 100 difference, then you need to be careful and suspicious. because he could be a fraud. so do not ever believe in a low price bidding model like this.

Regarding where the Bitcoin price is compared, maybe you can check it based on the price in each market (in general):

Now for some information on purchasing Bitcoin with a credit card, try checking here:

probably you can also compare not only the price but also the fee/cost to spend for this kind of transaction. Sometimes, they will be different.

I would suggest you to not make such generic topics and do some ground work and basic research when these questions usually come to the mind.

The above posts have highlighted some good ones among them. Make sure to use the one that allows citizens from the country where you reside or talk to the local community users first.

Now coming back to "price" - are you referring to transaction fees taken by the credit card company or the price of the cryptocurrency? Every exchange out there has some pros and cons. Now exchanges that accept credit/debit cards are going to have a significant fee for the payment processing. Also crypto price changes with time and therefore buying bitcoin would mean first you would to choose a price that you wish to buy because the fiat spent is fixed but the amount of bitcoin bought varies.
