There are four types of files you can download from English Toolbox, and each costs a different number of credits:
· MS Word files = 1 credit = $0.79 USD
· Interactive HTML file = 1 credit = $0.79 USD
· Audio MP3 files = 3 credits = $2.37 USD · Complete Lesson Plans in PDF format = 5 credits = $3.95 USD
The monthly subscription charge is $7.99 USD, which gives you ten credits to be used to buy a variety of exercises (for example, you could buy one audio file, 2 interactive exercises and 5 MS Word exercises, which would use up all of your 10 credits for the month). However, you may want to buy more credits in any given month. We therefore can offer you additional packages of credits for a lower cost-per-credit, which can be purchased once the initial 10 credits have been used up. The prices for these extra units are:
· Package of 5 = $3.69 USD (approx. $0.74 per credit)
· Package of 10 = $7.19 USD (approx. $0.72 per credit)
Once you finish downloading your initial 10 credits of materials, you will be asked if you wish to buy an additional package of 5 or 10 credits. When these are used up, you will be asked if you want to buy more, etc., until the end of your billing period. At the beginning of the next billing period, you will be billed for another 10 credits at $7.99 USD, and the process will start again.
