I'm not sure on this but I walked past a e-Pay sign recently and saw the Touch n Go logo there.

From their website, they do TnG as well.

And since Tesco uses e-pay, could it be possible to reload TnG in Tesco using cc? 

this is because only the shell heading to KL direction able to reload TnG using CC..and by RM100 per transaction..

It is possible that "quota habis".
I encountered this a few times during the period I went to reload TnG at a BHP station. They have a quota of RM1,000 each month, usually finished within 5days.

Reload on sunday Touch n go at salak south garden caltex, with 3% charges + 0.50 cents per transaction

Has anyone managed to reload TNG using hong leong Wise cc at KK Mart? Do they charge 50 sen for reload?

reloaded to my normal tng but get 95 points to my watson card as well. also, if without watson card, can't get the 5% rebate.

ahh i see, so the 5% rebate is not exclusive to watson card reload. good to know!

it's exclusive to watson card holders. but i know he meant not exclusive for the watson vip card (the watson card with tng feature). which means you can reload to any tng card, not compulsory must reload to the watson tng card. you just need to show your watson card as a proof that you are a member to get the 5% rebate (and of course to get the watson points as well).

ok, gotten the official T&C from Watson's service centre.

1) 5% rebate per RM100 reload.
2) Promo period until 21 May 2014.
3) Must reload into Watson's card (reason: auto-rebate upon reload)
4) While stocks last (??)

no idea about point 4. they have quota for this?

point 3, victorywp is lucky let's see if I can drop by that shop @ ss15 today.

Depends on how the system identify watson's card serial number (e.g. unique identifier), i wonder how they know if your reload credit is actually loaded into watson's card, not into other TnG card. Their tng terminals not linked with counter terminals anyway since they scan the TnG receipt into counter terminal to get the actual rebate

yeah, actually it depends on the worker whether to do it for you or not.
since as you said, the tng terminal is not linked with counter terminal.
all the best to watson ss15!
